Converting from one raid level to another, no changes
of stripes or stripesize can be requested because those
are subject to reshaping. I.e. the process requires to
takeover first and secondly request raid algorithm,
stripe or stripesize changes.
Ignore any related changes display warninngs
and proceed with the takeover.
Without this patch, a takeover requesting
stripesize change causes data corruption!
Just like with other vars support this:
make check_local T=xyz LVM_LOG_FILE_MAX_LINES=10000000
Allows easily to override existing line limit.
Also increase limiting size of logs per command since some of
our commands are becoming very verbose....
Add explaining message, when command was aborted due to the reach
of configure line number count (LVM_LOG_FILE_MAX_LINES)
for logging (used mainly with testing).
Last patch missed to mention, we've improved/fixed generated paths
in units and init.d shell scripts when lvm2 was plainly configured
with just i.e. --prefix.
Note: some distros might have fully specified --sbindir and
--usrsbindir - thus those very not seeing problems in generated paths.
Replace lowercase @sbindir@ with @SBINDIR@ which contains
fully decoded path.
Same with @usrsbindir@ which is also used with clvmd and cmirrord.
Also handle SYSCONFDIR for EnvironmentFile.
Patch fixes generated unit files with strings like:
ExecStart=${exec_prefix}/sbin/lvm
Introduce few more AC_SUBST vars for usage in *.in generation.
In some case we want to replace i.e. $sbindir with full path
instead of current ${exec_prefix}/sbin.
This patch provides:
USRSBINDIR
SBINDIR
DEFAULT_SYS_LOCK_DIR
SYSCONFDIR
At the same time properly use sbindir & usrsbindir with
lvm, fsadm, clvmd from one primary definition.
Do not allow to take snapshot of mirror/raid leg or log or metadata LV.
This was actually never supported, but user was able to create it,
and this put device stack in hardly fixable state (needs manual work).
This prevents such creation to pass.
Also improve validation when recreating snapshot volume type
from origin and COW volume.
Correction to function for extracting vgname out of lvconvert
parameters.
Avoid repeating some checks.
Add code to handle generic options which may provide vgname in its argument
and compare them all so they match to a single vgname (otherwise it's a
error).
Extract default (envvar) vgname only when no position nor optional vgname is
found.
Fixing regression instroduce with patchset started with commit:
1e2420bca8 (2.02.169)
split resize_crypt function in two.
a) Detect proper dm-crypt device type and count new --size
value for cryptsetup resize command.
b) Perform the resize
the bug in LUKS grow/shrink decision in fsadm was
masked due to fact that default LVM2 extent size
was larger than LUKS1 default data offset for dm-crypt
mapping. The new test address this bug.
lvcreate supports a 'conversion' when caching LV.
This normally worked fine, however in case passed LV was
thin-pool's data LV with suffix _tdata we have failed to early.
As the easiest fix looks dropping validation of name when
caching type is select - such name check will happen later
once the VG is opened again and properly detect if the LV
with protected name already exists and can be converted,
or will be rejected as ambigiuous operation requiring user
to specify --type cache | --type cache-pool.
Replaced the confusing device error message "not found (or ignored by
filtering)" by either "not found" or "excluded by a filter".
(Later we should be able to say which filter.)
Left the the liblvm code paths alone.
Fixes the following case with 3PVs and 3 legs "mirror" LV:
# lvcreate -l100%FREE --type mirror -m2 vg3
Insufficient free space for log allocation for logical volume .
Unable to allocate extents for mirror log.

Activation lock has a primary purpose to serialize locking of individual
LV in case there is no other protecting mechanism for parallel
execution.
However in the case an activated LV is composed from several other LVs,
noone should be able to manipulate with those LVs as well.
This patch add a very 'naive' global VG activation locking in this case.
In the future we may introduce smarter function detecting minimal closed
graph components if this will appear as bottleneck
Patch checks if the VG Write lock is held - in this case we do not
need any more locking - command has exclusive access to VG.
In case we have clustered VG and we are activating an LV which does not
need other LVs - we also do not need any more locks.
In all other cases take respective lock - for single LV - use lvid,
for complex LVs use vgname.
