This option could never have been printed in lvm2 metadata, so it could
be safely removed as it could have been set only as 0.
These configurable setting is supported via metadata profile.
Use single code to evaluate if the percentage value has
crossed threshold.
Recalculate amount value to always fit bellow
threshold so there are not need any extra reiterations
to reach this state in case policy amount is too small.
Since plugin's percentage compare has been fixed,
it's now revealed wrong compare here.
The logic for threshold is - to allow to go as high
as given value e.g. 80% - so if pool is exactlu 80%
full it's still allowed to use it (dmeventd will not
resize it).
Running "vgremove -f VG & pvs" results in the pvs
command reporting that the VG is not found or is
inconsistent. If the VG is gone or being removed,
the pvs command should just skip it and not print
errors about it.
"Not found" is because the pvs command created the
list of VGs to process, including VG, then vgremove
removed the VG, then the pvs command came to to read
the VG to process it and did not find it.
An "inconsistent" error could be reported if vgremove
had only partially completed removing VG when pvs did
vg_read on the VG to process it, causing pvs to find
the VG in a partially-removed state.
This fix adds a flag that pvs uses to ignore a VG
that can't be read or is inconsistent.
The lvmcache info might be resued, most notably in lvm shell.
We need to be sure that even lvmcache_info marked as invalid
is removed from the lvmcache so it does not confuse any subsequent
code/commands executed later on.
Problematic example with the lvm shell:
lvm> pvs
PV VG Fmt Attr PSize PFree
/dev/sda lvm2 --- 128.00m 128.00m
Before this patch (/dev/sda still displayed in a way):
======================================================
lvm> pvremove /dev/sda
Labels on physical volume "/dev/sda" successfully wiped
(without lvmetad)
lvm> pvs
No physical volume label read from /dev/sda
(with lvmetad)
lvm> pvs
PV VG Fmt Attr PSize PFree
/dev/sda lvm2 --- 128.00m 128.00m
With this patch applied:
========================
lvm> pvremove /dev/sda
Labels on physical volume "/dev/sda" successfully wiped
(without lvmetad)
lvm> pvs
(with lvmetad)
lvm> pvs
Before this patch:
$ lvs -a -o name,layout,role test/lvmlock
LV Layout Role
[lvmlock] linear public
With this patch applied:
$ lvs -a -o name,layout,role test/lvmlock
LV Layout Role
[lvmlock] linear private,lockd,sanlock
Add metadata_devices and seg_metadata_le_ranges report fields.
Currently only defined for raid, but should probably be extended
to all other segment types that don't report all their device
usage in the 'devices' field.
When a command does a sequence of
vg_write + vg_commit + vg_write + vg_commit,
initialization of non-PV devices happens during the
first vg_write, and does not need to be repeated by
the second vg_write.
When creating a lockd VG, this sequence occurs because
the VG is first created, then the lockd data is created,
then the lockd data is then written to the VG metadata.
Certain stacks of cached LVs may have unexpected consequences.
So add a warning function called when LV is cached to detect
such caces and WARN user about them - the best we could do ATM.
When we insert layer we also move status flag-bits for certain LV types,
so internal volume_group structure remains consistent.
(Perhaps it's misuse of 'insert_layer' function and we should have
another similar function for this.)
Basically we aim to maintain the same state as after reading fresh
metadata out of volume group.
Currently we when i.e. cache 'raid' LV - this should transfer 'raidLV' flag
to _corigin LV and cache is no longer a raid.
TODO: bits for stacked devices needs more exact rules.
Move code which runtime detects settings for cache_policy
out of config dir to cache seg handling code.
Also mark cache_mode as command profilable setting.
Revert back to already existing behavior which has been slightly
modified by a900d150e4.
At the end however it seem to be equal to change TID right with first
metadata write.
Existing code missed handling for 'unused' thin-pool which would
require to also check empty message list for TID==0.
So with the fix we now again preserve 'active' thin-pool volume
when first thin volume is created - this property was lost and caused
problems in cluster, where the lock was hold, but volume was no longer
active on the node.
Another missing part was the proper support for already increased,
but unfinished TID change.
So going back here with existing logic -
TID is increased with first MDA update.
Code allows start with either same TID or (TID-1).
If there are messages, TID must be lower by 1 for sending,
otherwise messages were already posted.
