[ClusterLabs] lvm on shared storage and a lot of...

[lejeczek]

.. device_block & device_unblock in dmesg.

and I see that the LVM resource would fail.
This to me seems to happen randomly, or I fail to spot a 
pattern.

Shared storage is a sas3 enclosure.
I believe I follow docs on LVM to the letter. I don't know 
what could be the problem.

would you suggest ways to troubleshoot it? Is it 
faulty/failing hardware?

many thanks,
L.
