Bug Fix

Doc Text:

When clustered locking was selected the command improperly passed locks around the cluster. This has made changing of the volume group clustering attribute malfunction. Code is now correctly checking and propagating locks even for non-clustered VGs when clustered locking is used.

Description of problem:
In this scenario, the snapshot volumes are already inactive before attemping to change the cluster attribute.

(...this deactivation always leaves dangling symlinks in /dev/vg/ for  all snapshot LVs in my case - I've filed a new udev bug #1141690 for that)

Comment 6 Zdenek Kabelac 2014-09-15 19:44:09 UTC

Test for active volumes is not correct - it's querying snap1 - while the only lock-holder is raid_1_6090.

I've been already suspecting there is somewhere a bug inside code which in some code paths may take wrong lock.

Comment 7 Zdenek Kabelac 2014-09-16 09:47:51 UTC

Upstream commit disables change of clustered attribute when any LV in VG is active:

http://www.redhat.com/archives/lvm-devel/2014-September/msg00084.html

Comment 8 Alasdair Kergon 2014-09-16 10:40:56 UTC

Please spell out in more detail why this change can no longer be applied to active linear and striped volumes like it used to be.

Comment 9 Corey Marthaler 2014-09-16 21:21:25 UTC

I forgot a step needed that the test was doing to cause this state, a rename of one of the snap volumes (and then a rename back).

Comment 10 Zdenek Kabelac 2014-09-17 06:50:09 UTC

Ahh ok - then we have the explanation for the lock being reported for the snapshot volume.

This has been already fixed with:

https://www.redhat.com/archives/lvm-devel/2014-September/msg00019.html

Another patch will still follow to reenable functionality for conversion to clustered volumes with active LVs.

Comment 11 Zdenek Kabelac 2014-09-17 13:32:40 UTC

So back to comment 8 -  problem goes around the fact that clvmd currently does not maintain locks for non-clustered LVs - the code is just skipped.

This lead to the problem that converted VG with active volumes was presented on the local node with 'active' LV - but they were active without holding and lock - thus remote nodes did not see proper lock status for such LV and basically nothing really worked.

2 upstream commits should renable support for conversion of VG with active LVs:

https://www.redhat.com/archives/lvm-devel/2014-September/msg00102.html
https://www.redhat.com/archives/lvm-devel/2014-September/msg00103.html

They just check if the LV is active and reactive them with local exclusive lock. If something fails - it's reported as an error and user has to manually fix problems.

The 'locking_type = 0' goes around all security checks and allows user to change this clustering attribute in no-matter-how-broken cluster is....

Comment 13 Corey Marthaler 2015-04-27 23:03:57 UTC

Fix verified in the latest rpms.
