When repairing thin pool or swapping thin pool metadata,
preserve chunk_size property and avoid to be automatically changed
later in the code to better match thin pool metadata size.
When raid leg is extracted, now the preload code handles this state
correctly and put proper new table entry into dm tree,
so the activation of extracted leg and removed metadata works
after commit.
It's not an error if the device is filtered out and hence cleared from
lvmetad cache - "pvscan --cache DevPath" has now the same behaviour in
this case as "pvscan --cache major:minor" (which is more consistent).
Before, the tests expected failure return code for "pvscan --cache DevicePath"
if the device was filtered (which is a different situation if the device
is missing in the system completely!).
Normally, if there are partitions defined on top of device-mapper
device, there should be a device-mapper device created for each
partiton on top of the old one and once the underlying DM device
is used by another devices (partition mappings in this case),
it can't be used as a PV anymore.
However, sometimes, it may happen the partition mappings are
missing - either the partitioning tool is not creating them if
it does not contain full support for device-mapper devices or
the mappings were removed.
Better safe than sorry - check for partition header on DM devs
and filter them out as unsuitable for PVs in case the check is
positive. Whatever the user is doing, let's do our best to prevent
unwanted corruption (...by running pvcreate on top of such device
that would corrupt the partition header).
We have to use empty list, not NULL if we want to denote that the list
has no items. Otherwise, the code further can segfault as it expects
there's always a sane value (= some list), including empty list,
but never NULL.
When we split leg from raid - we take a proper new lock for a new LV.
However for now activation checks only 'existince' of device UUID,
but it's not validating device has a proper name.
As a quick fix call suspend()/resume() to rename after split mirror.
When chunk size needs to be estimated, the code missed to round
to proper 64kb boundaries (or power of 2 for older thin pool driver).
So for some data and metadata size (i.e. 10GB and 4MB) it resulted
in incorrect chunk size (not being a multiple of 64KB)
Fix it by adding proper rounding and also use 1 routine for 2 places
where the same calculation is made.
Fix also incorrect printed warning that has used 'ffs()'
(which returns first 'least significant' bit in word)
and it was not really giving any useful size info and replace it
with properly estimated chunk size.
Make sure there is 'control' node before clvmd is started.
Somehow 'clvmd' is not allowed by selinux to create one.
TODO: Check is selinux policy is right here...
Since we support device stack of pools over pool
(thin-pool with cache data volume) the existing code
is no longer able to detect orphan _pmspare.
So instead do a _pmspare check after volume removal,
and remove spare afterwards.
Fixed syntax parsing means that some commands that used to work are now
failing. Particullary this case:
$ invalid lvcreate -l1 --type thin vg/pool
> Needs to fail becase thin type LV needs --virtualsize
$ invalid lvcreate --type snapshot vg/lv1
> Needs to fail because old-snapshot segment type needs --size
Some reported error messages have been also updated.
If we want to support conversion of VG to clustered type,
we currently need to relock active LV to get proper DLM lock.
So add extra loop after change of VG clustered attribute
to exlusively activate all active top level LVs.
When doing change -cy -> -cn we should validate LVs are not
active on other cluster nodes - we could be sure about this only
when with local exclusive activation - for other types
we require user to deactivate volumes first.
As a workaround for this limitation there is always
locking_type = 0 which amongs other skip the detection
of active LVs.
FIXME:
clvmd should handle looks for cluster locking type all the time.
While we could probably reacquire some type of lock when
going from non-clustered to clustered vg, we don't have any
single road back to drop the lock and keep LV active.
For now keep it safe and prohibit conversion when LV
is active in the VG.
We used to print an error message whenever we tried to deal with devices that
lvmetad knew about but were rejected by a client-side filter. Instead, we now
check whether the device is actually absent or only filtered out and only print
a warning in the latter case.
