When creating thin pool or check pool there is allocated LV
for metadata and for such allocation user should be able to
specify list of PVs on cmdline.
Also fix unused passed list of PV for thick to thin conversion,
where the code was using whole PV set from a VG (but since it's
been not enabled on cmdline, user could not hit this issue).
Also remove unneeded initialization of use_pvh.
When the import is used on a system, that uses devices file,
the final activation was impossible for the case the converted
volume was not present in devices file.
Currently add volume automatically in such case.
Also add some more debugging output from the script.
TODO: Consider enhnacing lvconvert with extending devices file.
VDO is using specific path for some device paths.
i.e. for /dev/sda it could be /dev/disk/by-id/scsi-xxxxx.
This used to be not a problem before lvm2 started to use snapshot,
but now it needs to replace matching device path.
So switch to the path naming used in vdoconf.yml file.
Add '--headings none|abbrev|full|0|1|2' command line option to select
the heading type.
none|0 - no headings
abbrev|1 - column name abbreviations
full|2 - full column names (column names are equal to exact names
that -o|--options also accepts to set report output)
Reuse existing report/headings config setting to make it possible to
change the type of headings to display:
0 - no headings
1 - column name abbreviations (default and original functionality)
2 - full column names (column names are equal to exact names that
-o|--options also accepts to set report output)
Also, add '--headings none|abbrev|full|0|1|2' command line option
so we are able to select the heading type for each LVM reporting
command directly.
Add new DM_REPORT_OUTPUT_FIELD_IDS_IN_HEADINGS report output flag.
If enabled, column IDs are reported instead of column names in report
headings.
The 'column IDs' are IDs as found in 'const struct dm_report_field_type *fields'
array that is passed during report initialization (that is, a call to
dm_report_init/dm_report_init_with_selection). In this case, the 'id'
dm_report_field_type member is used instead of the 'heading' member.
While create new LV for pool volume, use name from 'pool_metadata%d' naming
sequence. This LV is later on renamed to pool_t/cmeta, but if there
is any error in the middle, we may evenutally leave some 'volume',
With this name it can be slightly more obvious how it got there,
but also when we handle _pmspare name - we get slightly more predictible
name used there for it.
However for a standard usage this commit shall no visible impact as the
name is used temporarily just for cleaning LV.
Set the lock_args string in addition to doing initialization.
lvconvert calls lockd_init_lv_args() directly, skipping
the normal lockd_init_lv() which usually sets lock_args.
lvmlockd locking for swapmetadata adjusted for commit
ac36153e99 lvconvert: preserve UUID for swapped metadata
Now that the LV uuid is swapped between LVs, the lvmlockd lock can
simply be moved between them, and the same lock can continue to be
used for the LV outside of the pool.
Once lvm2 repairs pool's metadata LV and preserves the original metadata LV
with unmodified metadata, for such LV in VG use newly created UUID for new
_pmspare and actually preserve UUID for this hidden _pmspare (if it
exists).
The lockd lock needs to be freed for the LV that is becoming
the new metadata LV, and a new lockd lock needs to be created
for the old metadata LV that is becoming an independent LV.
