Switch METADATA_FORMAT flag usage to be stored via segtype
instead of 'status' flag which appeared to cause major
incompatibility troubles.
For backward compatiblity segtype flags are still accepted also
via 'status' bits which were used from version 2.02.169 so metadata
saved by this newer lvm2 version should still work nicely, although
new save version will no longer work on this older lvm2 version.
Allow storing LV status bits with segment type name field.
Switching to this since this field has better support for compatibility
with older version of lvm2 - since such unknown segtype will not cause
complete invisiblity of metadata from older lvm2 code - just the
particular LV will become unusable with unknown type of segment.
- Must reread all objects as PVs might be removed.
- Never consider testsuite provided PVs nested, or tearDown fails to
remove any outstanding VGs on them.
When 'fsadm' was running without terminal (i.e. pipe), it's been
automatically working like in '--yes'.
Detect terminal and only accept empty "" input in this mode.
Add more validation to catch mainly renamed devices, where
filesystem utils are not able to handle devices properly,
as they are not addressed by major:minor by rather via some
symbolic path names which can change over time via rename operation.
Since we add more validation to 'detect_mounted' function make sure
we always use it even with 'resize' action, so numerous validations
are not skipped.
Commit 5fe07d3574 failed to set raid5 types
properly on conversions from raid6. It always enforced raid6_ls_6
for types raid6/raid6_zr/raid6_nr/raid6_nc, thus requiring 3 conversions
instead of 2 when asking for raid5_{la,rs,ra,n}.

Offer possible interim LV types and display their aliases
(e.g. raid5 and raid5_ls) for all conversions between
striped and any raid LVs in case user requests a type
not suitable to direct conversion.
E.g. running "lvconvert --type raid5 LV" on a striped
LV will replace raid5 aka raid5_ls (rotating parity)
with raid5_n (dedicated parity on last image).
User is asked to repeat the lvconvert command to get to the
requested LV type (raid5 aka raid5_ls in this example)
when such replacement occurs.
Resolves: rhbz1439403
Add an exception to not allowing lvchange to change properties
on hidden LVs. When a thin pool data LV is a cache LV, we
need to allow changing cache properties on the tdata sublv of
the thin pool.
Trap cases where the percentage calculation currently leads to an empty
LV and the message:
Internal error: Unable to create new logical volume with no extents
Additionally convert the calculated number of extents from physical to
logical when creating a mirror using a percentage that is based on
Physical Extents. Otherwise a command like 'lvcreate -m3 -l80%FREE'
can never leave any free space.
This brings the behaviour closer to that of lvresize.
(A further patch is needed to cover all the raid types.)
_check_reappeared_pv() incorrectly clears the MISSING_PV flags of
PVs with unknown devices.
While one caller avoids passing such PVs into the function, the other
doesn't. Move the check inside the function so it's not forgotten.
Without this patch, if the normal VG reading code tries to repair
inconsistent metadata while there is an unknown PV, it incorrectly
considers the missing PVs no longer to be missing and produces
incorrect 'pvs' output omitting the missing PV, for example.
Easy reproducer:
Create a VG with 3 PVs pv1, pv2, pv3.
Hide pv2.
Run vgreduce --removemissing.
Reinstate the hidden PV pv2 and at the same time hide a different PV
pv3.
Run 'pvs' - incorrect output.
Run 'pvs' again - correct output.
See https://bugzilla.redhat.com/1434054
There are certain situations (not fully understood)
where is_missing_pv() is false, but pv->dev is NULL,
so this adds a check for NULL pv->dev after is_missing_pv()
to avoid a segfault.
With recent updates for thin pool monitoring in version 169
we lost multiple WARNINGs to be printed in syslog, when
pool crossed 80%, 85%, 90%, 95%, 100%.
Restore this logic as we want to keep user informed more
then just once when 80% boundary is passed.
Fix a regression introduced in 70bb726 that allows a local variable
in the monitored file checking routine to be accessed before its
assignment when the file has already been unlinked.
When a user does a Manager.PvCreate they can specify the block device using a
device path that may be different than what lvm reports is the device path. For
example a user could use:
/dev/disk/by-id/wwn-0x5002538500000000 instead of /dev/sdc
In this case the pvcreate will succeed, but when we query lvm we don't find the
newly created PV. We fail because it's device path is returned as /dev/sdc. This
change re-uses an internal lookup which can accommodate this and correctly find
the newly created PV.
