Patch 1b070f366b should have
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.
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.
event based autoactivation is now the only method that lvm
provides for autoactivation.
Setting lvm.conf event_activation=0 can still be used to disable
event based autoactivation commands, but doing so will no longer
enable static autoactivation.
new udev rule 69-dm-lvm.rules replaces
69-dm-lvm-meta.rules and lvm2-pvscan.service
udev rule calls pvscan directly on the added device
pvscan output indicates if a complete VG can be activated
udev env var LVM_VG_NAME_COMPLETE is used to pass complete
VG name from pvscan to the udev rule
udev rule uses systemd-run to run vgchange -aay <vgname>
Do not call 'dmsetup info' for non-dm devices.
Better handling for VGNAME and LVNAME - so when convering LV as
backend device automatically recognize it and reuse LV name for VDOLV.
Add prompt for final confirmation before actual conversion is started
(once confirmed, lvm2 commands no longer prompts to avoid leaving
conversion in the middle of its process.)
Add tool 'vdoimport' to support easy conversion of an existing VDO manager managed
VDO volumes into lvm2 managed VDO LV.
When physical converted volume is already a logical volume, conversion
happens with the VG itself, just with validation for extent_size, so
the virtually sized logical VDO volume size can be expressed in extents.
Example of basic simple usage:
vdoimport --name vg/vdolv /dev/mapper/vdophysicalvolume
Fsadm wants to print its own error message when it can't detect
type of the filesystem on a block device.
Otherwise fsadm exits with no message on an unused block device.
When blocksize --getsize64 gives empty result we want to fallback
to ancient --getsize * --getss calculation (RHBZ #1942486).

When 'fsadm resize vg/lv' is used without size, it should just
resize filesystem to match device - but since we now check
for unbound variable in bash - the previous usage no longer
works and needs explicit check.
Older blockdev tool return failure error code with --help,
and since now the tool abort on command failure, lets
detect missing --getsize64 support directly by running
command and check if it returns something usable.
It's likely very hard to have the system with
such old blockdev tool and newer lvm2 compiled.
Set more secure bash failure mode for pipilines.
Avoid using unset variables.
Enhnace error reporting for failing command.
Avoid using error via 'case..esac || error'.
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.
Make it possible to tear down VDO volumes with blkdeactivate if VDO is
part of a device stack (and if VDO binary is installed). Also, support
optional -o|--vdooptions configfile=file.
We already used Conflicts=shutdown target to stop LVM2 services on shutdown.
But we still missed the ordering - the shutdown.target should be reached
only after all the services are really stopped.
Reported here: https://github.com/lvmteam/lvm2/issues/17
The systemd generators are executed very early during the switch
from initramfs to system partition and the syslog is not yet fully
operational - it may cause blocking, if some debug logging is enabled
at the same time in /etc/lvm/lvm.conf log{} section.
To avoid timeouting and killing this generator - rather enhance lvm
code to suppress any syslog communication when LVM_SUPPRESS_SYSLOG
envvar is set.
Use of this envvar is needed since the parsing of i.e. cmdline options
that could eventually override lvm.conf setting happens in this case
way too late and number of lines could have been already streamed to
syslog.
Fix a scenario where global/event_activation setting is not found. In
this case we need to take default value just like lvm tools do when
executed. So use "lvmconfig --type full".
Also, if we fail to execute lvmconfig for whatever reason, fallback to
generating the activation units as failsafe action.
Reported by: Bastian Blank <waldi debian org>
The pvscan systemd service for autoactivation was
mistakenly dropped along with the lvmetad related
services.
The activation generator program now looks at the new
lvm.conf setting "event_activation" (default 1) to
switch between event activation and direct activation.
Previously, the old use_lvmetad setting was used to
switch between event and direct activation.
