48872b0369 integrity: avoid increasing logical block size of active LV
When adding integrity to an active LV, avoid choosing an
integrity block size that would result in increasing the
logical block size of the LV.

7b04ed07ba tests: integrity wait for sync
The test was using a raid+integrity LV without
first waiting for the integrity sync, which could
cause the test to fail (depending on init speed)
where it depends on integrity to work in uninitialized
areas.

Also use cmp instead of diff.

d9e8895a96 Allow dm-integrity to be used for raid images
dm-integrity stores checksums of the data written to an
LV, and returns an error if data read from the LV does
not match the previously saved checksum.  When used on
raid images, dm-raid will correct the error by reading
the block from another image, and the device user sees
no error.  The integrity metadata (checksums) are stored
on an internal LV allocated by lvm for each linear image.
The internal LV is allocated on the same PV as the image.

Create a raid LV with an integrity layer over each
raid image (for raid levels 1,4,5,6,10):

lvcreate --type raidN --raidintegrity y [options]

Add an integrity layer to images of an existing raid LV:

lvconvert --raidintegrity y LV

Remove the integrity layer from images of a raid LV:

lvconvert --raidintegrity n LV

Settings

Use --raidintegritymode journal|bitmap (journal is default)
to configure the method used by dm-integrity to ensure
crash consistency.

Initialization

When integrity is added to an LV, the kernel needs to
initialize the integrity metadata/checksums for all blocks
in the LV.  The data corruption checking performed by
dm-integrity will only operate on areas of the LV that
are already initialized.  The progress of integrity
initialization is reported by the "syncpercent" LV
reporting field (and under the Cpy%Sync lvs column.)

Example: create a raid1 LV with integrity:

$ lvcreate --type raid1 -m1 --raidintegrity y -n rr -L1G foo
  Creating integrity metadata LV rr_rimage_0_imeta with size 12.00 MiB.
  Logical volume "rr_rimage_0_imeta" created.
  Creating integrity metadata LV rr_rimage_1_imeta with size 12.00 MiB.
  Logical volume "rr_rimage_1_imeta" created.
  Logical volume "rr" created.
$ lvs -a foo
  LV                  VG  Attr       LSize  Origin              Cpy%Sync
  rr                  foo rwi-a-r---  1.00g                     4.93
  [rr_rimage_0]       foo gwi-aor---  1.00g [rr_rimage_0_iorig] 41.02
  [rr_rimage_0_imeta] foo ewi-ao---- 12.00m
  [rr_rimage_0_iorig] foo -wi-ao----  1.00g
  [rr_rimage_1]       foo gwi-aor---  1.00g [rr_rimage_1_iorig] 39.45
  [rr_rimage_1_imeta] foo ewi-ao---- 12.00m
  [rr_rimage_1_iorig] foo -wi-ao----  1.00g
  [rr_rmeta_0]        foo ewi-aor---  4.00m
  [rr_rmeta_1]        foo ewi-aor---  4.00m

3145a85583 pvck: repair headers and metadata
To write a new/repaired pv_header and label_header:

  pvck --repairtype pv_header --file <file> <device>

This uses the metadata input file to find the PV UUID,
device size, and data offset.

To write new/repaired metadata text and mda_header:

  pvck --repairtype metadata --file <file> <device>

This requires a good pv_header which points to one or two
metadata areas.  Any metadata areas referenced by the
pv_header are updated with the specified metadata and
a new mda_header. "--settings mda_num=1|2" can be used
to select one mda to repair.

To combine all header and metadata repairs:

  pvck --repair --file <file> <device>

It's best to use a raw metadata file as input, that was
extracted from another PV in the same VG (or from another
metadata area on the same PV.)  pvck will also accept a
metadata backup file, but that will produce metadata that
is not identical to other metadata copies on other PVs
and other areas.  So, when using a backup file, consider
using it to update metadata on all PVs/areas.

To get a raw metadata file to use for the repair, see
pvck --dump metadata|metadata_search.

List all instances of metadata from the metadata area:
  pvck --dump metadata_search <device>

Save one instance of metadata at the given offset to
the specified file (this file can be used for repair):

  pvck --dump metadata_search --file <file>
    --settings "metadata_offset=<off>" <device>

d1c5b3ae74 tests: avoid checking command result in cluster
When running cluster test with clvmd, the actual 'monitoring'
happens in cluster - so the 'already monitored' message
is also logged within clvmd code and the command cannot
see such effect.

clvmd was incapable to report this information back to command
so it cannot be displayed this way.

Add 'lvs -o+seg_monitor' validation which also works in clustered mode.
