warning.
Fix conversion to raid from striped lagging type.
Fix conversion to 'mirrored' mirror log with larger regionsize.
- Zero pool metadata on allocation (disable with allocation/zero_metadata=0).
- Failure in zeroing or wiping will fail command (bypass with -Zn, -Wn).
Fix running out of free buffers for async writing for larger writes.
Add integrity with raid capability.
Fix support for lvconvert --repair used by foreign apps (i.e. Docker).

From 48105f492f7f8c157ba714217ae55c6fb50e76c0 Mon Sep 17 00:00:00 2001
From: Maxim Plotnikov <wgh@torlan.ru>
Date: Wed, 22 Apr 2020 00:16:29 +0300
Subject: [PATCH] Fix scripts/lvmlocks.service.in using nonexistent --lock-opt
autowait
The --lock-opt autowait was dropped back in 9ab6bdce01,
and attempting to specify it has quite an opposite effect:
no waiting is done, which makes the unit almost useless.

Deduplication is a technique for reducing the consumption of storage
resources by eliminating multiple copies of duplicate blocks. Compression

-algorithms; these reduced blocks are then efficiently packed together into
-physical blocks. Thin provisioning manages the mapping from LBAs presented
-by VDO to where the data has actually been stored, and also eliminates any

+With deduplication, instead of writing the same data more than once, VDO detects and records each
+duplicate block as a reference to the original
block. VDO maintains a mapping from logical block addresses (used by the
storage layer above VDO) to physical block addresses (used by the storage
layer under VDO). After deduplication, multiple logical block addresses
may be mapped to the same physical block address; these are called shared
blocks and are reference-counted by the software.

+.SS 5. Usage of Discard/TRIM with a VDOLV
+You can discard data on a VDO LV and reduce used blocks on a VDOPoolLV.
+However, the current performance of discard operations is still not optimal
+and takes a considerable amount of time and CPU.
+Unless you really need it, you should avoid using discard.
+
+When a block device is going to be rewritten,
+block will be automatically reused for new data.
+Discard is useful in situations when it is known that the given portion of a VDO LV
+is not going to be used and the discarded space can be used for block
+provisioning in other regions of the VDO LV.
+For the same reason, you should avoid using mkfs with discard for
+a freshly created VDO LV to save a lot of time that this operation would
+take otherwise as device after create empty.
+.SS 6. Memory usage
+The VDO target requires 370 MiB of RAM plus an additional 268 MiB
+per each 1 TiB of physical storage managed by the volume.
+
+UDS requires a minimum of 250 MiB of RAM,
+which is also the default amount that deduplication uses.
+
+The memory required for the UDS index is determined by the index type
+and the required size of the deduplication window and
+is controlled by the \fBallocation/vdo_use_sparse_index\fP setting.
+
+With enabled UDS sparse indexing, it relies on the temporal locality of data
+and attempts to retain only the most relevant index entries in memory and
+can maintain a deduplication window that is ten times larger
+than with dense while using the same amount of memory.
+
+Although the sparse index provides the greatest coverage,
+the dense index provides more deduplication advice.
+For most workloads, given the same amount of memory,
+the difference in deduplication rates between dense
+and sparse indexes is negligible.
+
+A dense index with 1 GiB of RAM maintains a 1 TiB deduplication window,
+while a sparse index with 1 GiB of RAM maintains a 10 TiB deduplication window.
+In general, 1 GiB is sufficient for 4 TiB of physical space with
+a dense index and 40 TiB with a sparse index.
+.SS 7. Storage space requirements
+You can configure a VDOPoolLV to use up to 256 TiB of physical storage.
+Only a certain part of the physical storage is usable to store data.
+This section provides the calculations to determine the usable size
+of a VDO-managed volume.
+
+The VDO target requires storage for two types of VDO metadata and for the UDS index:
+.TP
+\(bu
+The first type of VDO metadata uses approximately 1 MiB for each 4 GiB
+of physical storage plus an additional 1 MiB per slab.
+.TP
+\(bu
+The second type of VDO metadata consumes approximately 1.25 MiB
+for each 1 GiB of logical storage, rounded up to the nearest slab.
+.TP
+\(bu
+The amount of storage required for the UDS index depends on the type of index
+and the amount of RAM allocated to the index. For each 1 GiB of RAM,
+a dense UDS index uses 17 GiB of storage and a sparse UDS index will use
+170 GiB of storage.
