The autoactivation property can be specified in lvcreate
or vgcreate for new LVs/VGs, and the property can be changed
by lvchange or vgchange for existing LVs/VGs.
--setautoactivation y|n
enables|disables autoactivation of a VG or LV.
Autoactivation is enabled by default, which is consistent with
past behavior. The disabled state is stored as a new flag
in the VG metadata, and the absence of the flag allows
autoactivation.
If autoactivation is disabled for the VG, then no LVs in the VG
will be autoactivated (the LV autoactivation property will have
no effect.) When autoactivation is enabled for the VG, then
autoactivation can be controlled on individual LVs.
The state of this property can be reported for LVs/VGs using
the "-o autoactivation" option in lvs/vgs commands, which will
report "enabled", or "" for the disabled state.
Previous versions of lvm do not recognize this property. Since
autoactivation is enabled by default, the disabled setting will
have no effect in older lvm versions. If the VG is modified by
older lvm versions, the disabled state will also be dropped from
the metadata.
The autoactivation property is an alternative to using the lvm.conf
auto_activation_volume_list, which is still applied to to VGs/LVs
in addition to the new property.
If VG or LV autoactivation is disabled either in metadata or in
auto_activation_volume_list, it will not be autoactivated.
An autoactivation command will silently skip activating an LV
when the autoactivation property is disabled.
To determine the effective autoactivation behavior for a specific
LV, multiple settings would need to be checked:
the VG autoactivation property, the LV autoactivation property,
the auto_activation_volume_list. The "activation skip" property
would also be relevant, since it applies to both normal and auto
activation.
Switch to plain 'kill' we should no longer need SIGKILL
as polling can be interrupted.
Resolve problem in aux wait_pvmove_lv_ready() that was using
lvm command to check for UUID - but this was interferring with
VG lock and it's been delaying confirmation.
So reducing slow-down of test - so it can run faster.
Looks like there was some missed versioning increase during devel.
So with kernel >= 4.18 version 1.19 is enough to look like 1.20
However backported 1.19 targets seems to not provide all
the capabilities.
Test has to use PV with suffix pv[0..9] otherwise
it's ignored by test suite filter.
Better fix for VG names to use prefix LVMTEST.
Skip the test for runs without LVM_TEST_DEVDIR != /dev
Always use PREFIX for vg header - all tests must use this prefix,
VGs without are not allowed.
Modify pv_symlink test - as the test was checking unsupportable
combination - since lvm2 commands withing testsuite are only
allowed to manipulate with /dev/mapper/LVMTESTXXXX path -
nothing else allowed and fails on being filtered.
Added comment the 'lvs' already initiates dmeventd
Note: we don't have any query mechanism to check if dmeventd
is already running except access of socket which basically
starts dmeventd if it's not running.
For determinist test results lvm2/dm service shall not be present
and running in the system as it may randomize test results.
In case they are found present, this test ends with warning (not failure).
Some older instancies of 'mdadm' opened legs in RW and
closed and opened again and expected exlusive access.
But here udev rule can be fired - so on these versions
slow down whole mdadm runtime by using strace, to
give system a bit more time to finish udev rule.
Make check_lvmpolld_init_rq_count() more compatible with older gawk,
where some functionality was not working properly.
Also change 'not not' condition.
Just like lvm command ignores 0/xxxx report from judging the status.
Avoid using infinite loop and limit report checking to 100 checks.
If it would need more - something is not right.
Our tests may result in producation of huge set of
invalid links in /dev/disk directory depeding on version
of udev and various kinds of failures.
Also we happen to invoke some on-system pvscans generating
local /etc/lvm/archive & backups - remove them when
test is finished.
Try to synchronize with colliding udev.
Also retry once if there is some failure with some
sleep between next retry.
Use oflag=direct for wipping without wipefs.
Combination of throttling and slowed device is a bit faster.
Also add FIXME about the mutliple spawn polling processing
when activating invidual LV for a pvmove.
