 Help bootstrapping existing shared vgs into the devices file.
 Reading the vg in vgimportdevices would require locking to be
 started, but vgchange lockstart won't see the vg if it's not
 in the devices file.  The lvmlockd locks are not protecting
 vg modifications so skipping them here won't be a problem.

 Subject: [PATCH 06/54] filter-sysfs: skip when device id is set
 When a device id is set for a device, using an idtype other
 than devname, it means that sysfs has been used with the device
 to match the device id.  So, checking for a sysfs entry for the
 device in filter-sysfs is redundant.  For any other cases not
 covered by this (e.g. devname ids), have filter-sysfs simply
 stat /sys/dev/block/major:minor to test if the device exists
 in sysfs.
 The extensive processing done by filter-sysfs init is removed.
 It was taking an immense amount of time with many devices, e.g.
 . 1024 PVs in 520 VGs
 . 520 concurrent vgchange -ay <vgname> commands
 . vgchange scans only PVs in the named VG (based on pvs_online
  files from a pending patch)
 A large number of the vgchange commands were taking over 1 min,
 and nearly half of that time was used by filter-sysfs init.
 With this patch, the vgchange commands take about half the time.

 Subject: [PATCH 08/13] Allow system.devices to be automatically created on
 first boot
 An OS installer can create system.devices for the system and
 disks, but an OS image cannot create the system-specific
 system.devices.  The OS image can instead configure the
 image so that lvm will create system.devices on first boot.
 Image preparation steps to enable auto creation of system.devices:
 - create empty file /etc/lvm/devices/auto-import-rootvg
 - remove any existing /etc/lvm/devices/system.devices
 - enable lvm-devices-import.path
 - enable lvm-devices-import.service
 On first boot of the prepared image:
 - udev triggers vgchange -aay --autoactivation event <rootvg>
 - vgchange activates LVs in the root VG
 - vgchange finds the file /etc/lvm/devices/auto-import-rootvg,
  and no /etc/lvm/devices/system.devices, so it creates
  /run/lvm/lvm-devices-import
 - lvm-devices-import.path is run when /run/lvm/lvm-devices-import
  appears, and triggers lvm-devices-import.service
 - lvm-devices-import.service runs vgimportdevices --rootvg --auto
 - vgimportdevices finds /etc/lvm/devices/auto-import-rootvg,
  and no system.devices, so it creates system.devices containing
  PVs in the root VG, and removes /etc/lvm/devices/auto-import-rootvg
  and /run/lvm/lvm-devices-import
 Run directly, vgimportdevices --rootvg (without --auto), will create
 a new system.devices for the root VG, or will add devices for the
 root VG to an existing system.devices.

 Previous commit 82617852a4d3c89b09124eddedcc2c1859b9d50e
 introduce bug in complession - as the rl_completion_matches()
 needs to always advance to next element where the index
 is held in static variable.
 Add comment about this usage.

 Subject: [PATCH 10/54] device_id: fix search on filtered device
 When devnames are used as device ids and devnames change,
 then new devices need to be located for the PVs.  If the old
 devname is now used by a filtered device, this was preventing
 the code from searching for the new device, so the PV was
 reported as missing.

 Subject: [PATCH 10/13] vgimportdevices: skip global lockd locking
 Fix commit b65a2c3f3a767 "vgimportdevices: skip lvmlockd locking"
 which intended to disable lvmlockd locking, but the lockd_gl_disable
 flag was mistakenly set after lock_global() so it wasn't effective.
 This caused vgimportdevices to fail unless locking was started.

 Subject: [PATCH 11/54] device_id: searched_devnames improvements
 Remove the searched_devnames file in a couple more places:
 . When hints need refreshing it's possible that a missing
  devices file entry could be found by searching devices
  again.
 . When a devices file entry devname is first found to be
  incorrect, a new search for missing entries may be
  useful.

 Subject: [PATCH 12/13] lvmlockd: avoid lockd_vg for local VGs
 Previously, a command would call lockd_vg() for a local VG,
 which would go to lvmlockd, which would send back ENOLS,
 and the command would not care when it saw the VG was local.
 The pointless back-and-forth to lvmlockd for local VGs can
 be avoided by checking the VG lock_type in lvmcache (which
 label_scan now saves there; this wasn't the case back when
 the original lockd_vg logic was added.)  If the lock_type
 saved during label_scan indicates a local VG, then the
 lockd_vg step is skipped.

 Subject: [PATCH 14/14] lv_manip: avoid unreleased memory pool(s) message on
 RAID extend
 In case of different PV sizes in a VG, the lvm2 allocator falls short
 to define extended segments resiliently asked for 100%FREE RaidLV extension
 and a RAID distinct allocation check fails.  Fix is to release a memory pool
 on the resulting error path.
 Until the lvm2 allocator gets enhanced (WIP) to do such complex (and other)
 allocations proper, a workaround is to extend a RaidLV to any free space on
 its already allocated PVs by defining those PVs on the lvextend command line
 then iteratively run further such lvextend commands to extend it to its
 final intended size.  Mind, this may be a non-trivial extension interation.
 (cherry picked from commit 557b2850cef7fa49e2cbacd36e77f679181f09ae)

 +.SH NAME
 +.
 +lvmautoactivation \(em LVM autoactivation
 +.
 +.SH DESCRIPTION
 +.
 +Autoactivation is the activation of LVs performed automatically by the
 +system in response to LVM devices being attached to the machine.  When all
 +PVs in a VG have been attached, the VG is complete, and LVs in the VG are
 +activated.
 +.P
 +Autoactivation of VGs, or specific LVs, can be prevented using vgchange or
 +lvchange --setautoactivation n.  The lvm.conf auto_activation_volume_list
 +is another way to limit autoactivation.
 +.P
 +The most common form of autoactivation is "event based", in which complete
 +VGs are activated in response to uevents which occur during system startup
 +or at any time after the system has started.  Another form of
 +autoactivation is "service based" in which complete VGs are activated at a
 +fixed point during system startup by a systemd service, and are not
 +activated in response to uevents.  This can be controlled with the
 +lvm.conf setting event_activation.
 +.P
 +Event based autoactivation is driven by udev, udev rules, and systemd.
 +When a device is attached to a machine, a uevent is generated by the
 +kernel to notify userspace of the new device.  systemd-udev runs udev
 +rules to process the new device.  Udev rules use blkid to identify the
 +device as an LVM PV and then execute the lvm-specific udev rule for the
 +device, which triggers autoactivation.
 +.P
 +There are two variations of event based autoactivation that may be used a
 +system, depending on the LVM udev rule that is installed (found in
 +/lib/udev/rules.d/.)  The following summarizes the steps in each rule
 +which lead to autoactivation:
 +.P
 +.B 69-dm-lvm-metad.rules
 +.
 +.IP \[bu] 2
 +device /dev/name with major:minor X:Y is attached to the machine
 +.
 +.IP \[bu] 2
 +systemd/udev runs blkid to identify /dev/name as an LVM PV
 +.
 +.IP \[bu] 2
 +udev rule 69-dm-lvm-metad.rules is run for /dev/name
 +.
 +.IP \[bu] 2
 +the lvm udev rule runs the systemd service lvm2-pvscan@X:Yservice
 +.
 +.IP \[bu] 2
 +the lvm2-pvscan service runs:
 +.br
 +pvscan --cache -aay --major X --minor Y
 +.
 +.IP \[bu] 2
 +pvscan reads the device, records that the PV is online
 +(see pvs_online), and checks if the VG is complete.
 +.
 +.IP \[bu] 2
 +if the VG is complete, pvscan creates the vgs_online temp file,
 +and activates the VG.
 +.
 +.IP \[bu] 2
 +the activation command output can be seen from
 +systemctl status lvm2-pvscan*
 +.P
 +.B 69-dm-lvm.rules
 +.
 +.IP \[bu] 2
 +device /dev/name with major:minor X:Y is attached to the machine
 +.
 +.IP \[bu] 2
 +systemd/udev runs blkid to identify /dev/name as an LVM PV
 +.
 +.IP \[bu] 2
 +udev rule 69-dm-lvm.rules is run for /dev/name
 +.
 +.IP \[bu] 2
 +the lvm udev rule runs:
 +.br
 +pvscan --cache --listvg --checkcomplete --vgonline
 +.br
 +--autoactivation event --udevoutput --journal=output /dev/name
 +.
 +.IP \[bu] 2
 +pvscan reads the device, records that the PV is online
 +(see pvs_online), and checks if the VG is complete.
 +.
 +.IP \[bu] 2
 +if the VG is complete, pvscan creates the vgs_online temp file,
 +and prints the name of the VG for the udev rule to import:
 +LVM_VG_NAME_COMPLETE='vgname'
 +.
 +.IP \[bu] 2
 +if the lvm udev rule sees LVM_VG_NAME_COMPLETE from pvscan,
 +it activates the VG using a transient systemd service named
 +lvm-activate-<vgname>.
 +.
 +.IP \[bu] 2
 +the lvm-activate-<vgname> service runs
 +.br
 +vgchange -aay --autoactivation event <vgname>
 +.
 +.IP \[bu] 2
 +the activation command output can be seen from
 +systemctl status lvm-activate-<vgname>
 +.P
 +.
 +.SS pvscan options
 +.P
 +.B --cache
 +.br
 +Read the <device> arg (and only that device), and record that
 +the PV is online by creating the /run/lvm/pvs_online/<pvid>
 +file containing the name of the VG and the device for the PV.
 +.P
 +.B -aay
 +.br
 +Activate the VG from the pvscan command
 +(includes implicit --checkcomplete and --vgonline.)
 +.P
 +.B --checkcomplete
 +.br
 +Check if the VG is complete, i.e. all PVs are present on
 +the system, by checking /run/lvm/pvs_online/<pvid> files.
 +.P
 +.B --vgonline
 +.br
 +Create /run/lvm/vgs_online/<vgname> if the VG is complete
 +(used to ensure only one command performs activation.)
 +.P
 +.B --autoactivation event
 +.br
 +Inform the command it is used for event based autoactivation.
 +.P
 +.B --listvg
 +.br
 +Print the name of the VG using the device.
 +.P
 +.B --udevoutput
 +.br
 +Only print output that can be imported to the udev rule,
 +using the udev environment key format, i.e. NAME='value'.
 +.P
 +.B --journal=output
 +.br
 +Send standard command output to the journal (when stdout
 +is reserved for udev output.)
 +.P
 +.SS Temp files
 +.P
 +Autoactivation commands use a number of temp files in /run/lvm (with the
 +expectation that /run is cleared between boots.)
 +.P
 +.B pvs_online
 +.br
 +pvscan --cache creates a file here for each PV that is attached.  The file
 +is named with the PVID and contains the VG name and device information.
 +The existence of the file is used to determine when all PVs for a given VG
 +are present.  The device information in these files is also used to
 +optimize locating devices for a VG when the VG is activated.
 +.P
 +.B pvs_lookup
 +.br
 +pvscan --cache creates a file here named for a VG (if one doesn't already
 +exist.)  The file contains a list of PVIDs in the VG.  This is needed when
 +a PV is processed which has no VG metadata, in which case the list of
 +PVIDs from the lookup file is used to check if the VG is complete.
 +.P
 +.B vgs_online
 +.br
 +The first activation command (pvscan or vgchange) to create a file here,
 +named for the VG, will activate the VG.  This resolves a race when
 +concurrent commands attempt to activate a VG at once.
 +.

 +.SS static autoactivation
 +.P
 +When event autoactivation is disabled by setting lvm.conf
 +event_activation=0, autoactivation is performed at one or more static
 +points during system startup. At these points, a vgchange -aay command is
 +run to activate complete VGs from devices that are present on the system
 +at that time. pvscan commands (and lvm2-pvscan services) do not perform
 +autoactivation in this mode.  pvscan commands may still be run from
 +uevents but will do nothing when they read the event_activation=0 setting.
 +.P
 +The static vgchange -aay commands are run by three systemd services at
 +three points during startup: lvm2-activation-early, lvm2-activation, and
 +lvm2-activation-net. These static activation services are "generated
 +services", so the service files are created at run time by the
 +lvm2-activation-generator command (run by systemd).
 +lvm2-activation-generator creates the services if lvm.conf
 +event_activation=0.
 +.P
 +The limitation of this method is that devices may not be attached to the
 +system (or set up) at a reliable point in time during startup, and they
 +may not be present when the services run vgchange.  In this case, the VGs
 +will not be autoactivated.  So, the timing of device attachment/setup
 +determines whether static autoactivation will produce the same results as
 +event autoactivation.  For this reason, static autoactivation is not
 +recommended.
 +.P
 +Sometimes, static autoactivation is mistakenly expected to disable all
 +autoactivation of particular VGs. This may appear to be effective if those
 +VGs are slow to be attached or set up. But, the only correct and reliable
 +way to disable autoactivation is using vgchange/lvchange
 +--setautoactivation n, or lvm.conf auto_activation_volume_list.

 Subject: [PATCH 28/54] devices: exclude multipath components based on matching
 wwid
 If multipath component devices get through the filter and
 cause lvm to see duplicate PVs, then check the wwid of the
 devs and drop the component devices as if they had been
 filtered.  If a dm mpath device was found among the duplicates
 then use that as the PV, otherwise do not use any of the
 components as the PV.
 "duplicate PVs" associated with multipath configs will no
 longer stop commands from working.

 Subject: [PATCH 29/54] devices: exclude md components when duplicate pvs are
 seen
 Improve handling of md components that get through the
 filter, like the previous improvement for multipath.
 If md components get through the filter and trigger
 duplicate PV code, then eliminate any devs entirely
 that are not an md device.

 Subject: [PATCH 30/54] lvmdevices: fix checks when adding entries
 Removes some incorrect and unnecessary checks for other entries
 when adding a new devices.  The removed checks and corrections were
 mostly redundant with what is already done by device id matching.
 Other checking is reworked so the warnings are a bit different.

 Subject: [PATCH 32/54] devices file: do not clear PVID of unread devices
 In a certain disconnected state, a block device is present on
 the system, can be opened, reports a valid size, reports the
 correct device id (wwid), and matches a devices file entry.
 But, reading the device can still fail.  In this case,
 device_ids_validate() was misinterpreting the read error as
 the device having no data/label on it (and no PVID).
 The validate function would then clear the PVID from the
 devices file entry for the device, thinking that it was
 fixing the devices file (making it consistent with the on disk
 state.)  Fix this by not attempting to check and correct a
 devices file entry that cannot be read.  Also make this case
 explicit in the hints validation code (which was doing the
 right thing but indirectly.)

 Subject: [PATCH 36/54] devices: drop incorrect paths from aliases list
 along with some basic checks for cases when a device
 has no aliases.
 lvm itself creates many situations where a struct device
 has no valid paths, when it activates and opens an LV,
 does something with it, e.g. zeroing, and then closes
 and deactivates it.  (dev-cache is intended for PVs, and
 the use of LVs should be moved out of dev-cache in a
 future patch.)

 Subject: [PATCH 37/54] devices: initial use of existing option
 Use dev_cache_get_existing() in a few common, high level
 locations where it's obvious that only existing dev-cache
 entries are wanted.  This can be expanded and used in more
 locations (or dev_cache_get can stop creating new entries.)

 Subject: [PATCH 38/54] devices: fix dev_name assumptions
 dev_name(dev) returns "[unknown]" if there are no names
 on dev->aliases.  It's meant mainly for log messages.
 Many places assume a valid path name is returned, and
 use it directly.  A caller that wants to use the path
 from dev_name() must first check if the dev has any
 paths with dm_list_empty(&dev->aliases).

 Subject: [PATCH 42/54] vgimportdevices: fix incorrect deviceidtype usage
 When a VG has PVs with different device id types,
 it would try to use the idtype of the previous PV
 in the loop.  This would produce an unncessary warning,
 or could lead to using the devname idtype when a better
 idtype is available.

 Subject: [PATCH 45/54] filter-mpath: use multipath blacklist
 Explicit wwid's from these sections control whether the
 same wwid in /etc/multipath/wwids is recognized as a
 multipath component.  Other non-wwid keywords are not
 used, and may require disabling the use of the multipath
 wwids file in lvm.conf.

 Subject: [PATCH 48/54] toollib: fix segfault when handling selection with
 historical LVs
 When processing historical LVs inside process_each_lv_in_vg for
 selection, we need to use dummy "_historical_lv" for select_match_lv.
 This is because a historical LV is not an actual LV, but only a tiny
 representation with subset of original properties that we recorded
 (name, uuid...).
 To use the same processing functions we use for full-fledged non-historical
 LVs, we need to use the prefilled "_historical_lv" structure which has all
 the other missing properties hard-coded.

 A typo of the filename after --devicesfile should result in a
 command error rather than the command falling back to using no
 devices file at all.  Exception is vgcreate|pvcreate which
 create a new devices file if the file name doesn't exist.

 Subject: [PATCH 51/54] filter-mpath: handle other wwid types in blacklist
 Fixes commit 494372b4eed0c8f6040e3357939eb7511ac25745
  "filter-mpath: use multipath blacklist"
 to handle wwids with initial type digits 1 and 2 used
 for t10 and eui ids.  Originally recognized type 3 naa.

 Subject: [PATCH 52/54] vdo: fix conversion of vdo_slab_size_mb
 When converting VDO volume, the parameter vdo_slabSize was
 incorrectly copied as vdo_blockMapCacheSize, however this parameter
 is then no longer used for any table line creation so the wrong
 value was only stored in metadata.
 Also use just single get_kb_size_with_unit_ and remove it's duplicate
 functionality with get_mb_size_with_unit_.
 Use $VERB for vdo remove call.

 Subject: [PATCH 53/54] filter-mpath: get wwids from sysfs vpd_pg83
 to compare with wwids in /etc/multipath/wwids when
 excluding multipath components.  The wwid printed
 from the sysfs wwid file may not be the wwid used
 in multipath wwids.  Save the wwids found for each
 device on dev->wwids to avoid repeating reading
 and parsing the sysfs files.

 Subject: [PATCH] apply multipath_component_detection=0 to duplicate PV
 handling
 multipath_component_detection=0 has always applied to the filter-based
 component detection.  Also apply this setting to the duplicate-PV
 handling which also eliminates multipath components (based on duplicate
 PVs having the same wwid.)
 (cherry picked from commit 99ce09ae778c2cc4aa2611e425bba5287b8b9513)

 Subject: [PATCH 1/4] vgimportdevices: change result when devices are not added
 When using --all, if one VG is skipped, continue adding
 other VGs, and do not return an error from the command
 if some VGs are added. (A VG is skipped if it's missing PVs.)
 If the command fails during devices file setup or device
 scanning, then remove the devices file if it has been
 newly created by the command, and exit with an error.
 If devices from a named VG are not imported (e.g. the
 VG is missing devices), then remove the devices file if
 it has been newly created by the command, and exit with
 an error.
 If --all VGs are being imported, and no devices are found
 to include in the devices file, then remove the devices
 file if it has been newly created by the command, and
 exit with an error.

 Subject: [PATCH 2/4] vgimportdevices: fix locking when creating devices file
 Take the devices file lock before creating a new devices file.
 (Was missed by the change to preemptively create the devices
 file prior to setup_devices(), which was done to improve the
 error path.)

 Subject: [PATCH 3/4] thin: fix message processing on thin-pool extension
 When thin-pool had queued some delete message on extension operation
 such message has been 'lost' and thin-pool kernel metadata has been
 left with a thin volume that no longer existed for lvm2 metadata.
 (cherry picked from commit 09371131469f7398c597a5fb30dc565859253cc2)

 Subject: [PATCH 2/3] vdo: use defines also for configuration defines
 Keep single source for most of values printed in lvm.conf
 (still needs some conversion)
 Correct max for logical threads to 60
 (we may refuse some older configuration which might eventually
 user higher numbers - but so far let's assume no user have ever set this
 as it's been non-trivial and if would complicate code unnecessarily.)
 Accept maximum of 4PiB for virtual size of VDO LV
 (lvm2 will drop 'header borders to 0 for this case').
 (cherry picked from commit b5c8e591ed9ee30b67e79d60705d3c0bb8509a2a)

 Subject: [PATCH 070/115] vdo: fix conversion of vdo_slab_size_mb
 When converting VDO volume, the parameter vdo_slabSize was
 incorrectly copied as vdo_blockMapCacheSize, however this parameter
 is then no longer used for any table line creation so the wrong
 value was only stored in metadata.
 Also use just single get_kb_size_with_unit_ and remove it's duplicate
 functionality with get_mb_size_with_unit_.
 Use $VERB for vdo remove call.

 Subject: [PATCH 071/115] tests: add lvm_vdo_wrapper
 Introduce a replacement vdo manager wrapper for testing.
 When using test suite on a system without vdo manager (which has got
 deprecated) - we still need its functionality to prepare 'vdo volume'
 for testing lvm_import_vdo.
 Wrapper currently need 2 binaries from older 'vdo 6.2' package -
 to be named:
 oldvdoformat - format VDO metadata with older format
 oldvdoprepareforlvm - shift vdo metadata by 1MiB

 Subject: [PATCH 072/115] tests: update for wrapper
 Update calling vdo manager since our vdo wrapper has a simple shell
 arg parser so it needs args without '='
 Also correct using  DM_DEV_DIR for 'pvcreate'

 been already fixing this issue but since it the incorrect
 patch rebasing the change to vdo_slabSize got lost.
 So again now with explicit one-line patch.

 Subject: [PATCH 076/115] vdo: check vdo memory constrains
 Add function to check for avaialble memory for particular VDO
 configuration - to avoid unnecessary machine swapping for configs
 that will not fit into memory (possibly in locked section).
 Formula tries to estimate RAM size machine can use also with
 swapping for kernel target - but still leaving some amount of
 usable RAM.
 Estimation is based on documented RAM usage of VDO target.
 If the /proc/meminfo would be theoretically unavailable, try to use
 'sysinfo()' function, however this is giving only free RAM without
 the knowledge about how much RAM could be eventually swapped.
 TODO: move _get_memory_info() into generic lvm2 API function used
 by other targets with non-trivial memory requirements.

 Subject: [PATCH 077/115] vdo: add reformating to extent size aligned virtual
 size
 Newer VDO kernel target require to have matching virtual size - this
 however cause incompatiblity when lvcreate is let to format VDO data
 device and read the usable size from vdoformat.
 Altough this is a kernel regression and will likely get fixed,
 lvm2 can actually reformat VDO device to use properly aligned VDO LV
 size to make this problem disappear.
 (cherry picked from commit a477490e812639fed3be495f215fcf1a7b65b7ee)

 When creating VDO pool based of  % values, lvm2 is now more clever
 and avoids to create 'unsupportable' sizes of physical backend
 volumes as 16TiB is maximum size supported by VDO target
 (and also limited by maximum supportable slabs (8192) based on slab
 size.
 If the requested virtual size is approaching max supported size 4PiB,
 switch header size to 0.

 Subject: [PATCH 081/115] vdo: use only verbose log level for reformating
 When lvcreate is makeing VDO pool and user has not specified -V size,
 ATM we actually run  'vdoformat' twice to get properly 'extent' aligned
 size matching lvm2 properties - so the 2nd. run of vdoformat actually
 can stay with 'log_verbose()' so the standard printed result
 is not showing confusing info (which is now also correctly using
 print_unless_silent)

 Subject: [PATCH 083/115] vdo: extend volume and pool without flush
 When the volume size is extended, there is no need to flush
 IO operations (nothing can be targeting new space yet).
 VDO target is supported as target that can safely work with
 this condition.
 Such support is also needed, when extending VDOPOOL size
 while the pool is reaching its capacity - since this allows
 to continue working without reaching 'out-of-space' condition
 due to flushing of all in flight IO.

 Subject: [PATCH 085/115] device_mapper: add parser for vdo metadata
 Add very simplistic parser of vdo metadata to be able to obtain
 logical_blocks stored within vdo metadata - as lvm2 may
 submit smaller value due to internal aligment rules.
 To avoid creation of mismatching table line - use this number
 instead the one provided by lvm2.

 From 13ce88a2b204e9b05206b624bbcca00446312ebb Mon Sep 17 00:00:00 2001
 From: Zdenek Kabelac <zkabelac@redhat.com>
 Date: Wed, 26 Oct 2022 14:38:29 +0200
 Subject: [PATCH 086/115] dev_manager: accept misalined vdo pools.
 Since lvm2 may create VDO pool virtual size aligned only on extent size
 while VDO itself is just 4K aligned - we need to support such misalign.
 (cherry picked from commit 2e79b005c2013fb03d8a48a3cfd8e70a982dd65b)
