Change patch format to remove Git version
* Patches 0001-0122 only have the patch format modified
Update to the head of the upstream staging branch plus redhat patches
* Patches 0123-0134 & 1036-0142 are from the upstream staging branch
* Patches 0143-1046 have been submitted upstream
* Patch 0156 is a Red Hat only patch. Red Hat udev rules set ID_SERIAL
from 60-persistent-storage.rules instead of 55-scsi-sg3_id.rules.
Multipath's parse_vpd_pg83() function needs to match the ID_SERIAL
value from udev.
Rename files
* Previous patches 0123-0132 are now patches 1035 & 0147-0155

Subject: [PATCH] 11-dm-mpath.rules: run "multipath -U" with -v1
|
|
|
|
In cases where some path devices are temporarily unavailable (e.g. failover),
|
|
high amounts of error messages such as these are seen:
|
|
|
|
Feb 27 08:02:03 ictm1608s02h1 multipath[1420]: get_udev_device: failed to look up 65:224 with type 1
|
|
Feb 27 08:02:03 ictm1608s02h1 multipath[1420]: 3600a098000aada210000f1625de51ed9: discarding non-existing path 65:224
|
|
|
|
This is because every invocation of "multipath -U" prints these messages
|
|
at the default log level (-v2). In the case of "multipath -U", these
|
|
messages aren't important, and in failover situations, "multipath -U" is
|
|
run pretty often, spamming the log with many similar messages.
|
|
|
|
Generally reducing the log level of these messages would be wrong,
|
|
because they are important for multipathd's operation, to verify that
|
|
multipathd does the right thing when discovering a discrepancy between the dm
|
|
state and the devices present in the system. Therefore, just decrease the
|
|
verbosity with which we invoke "multipath -U" in the udev rules.
