Description Fabio Massimo Di Nitto 2013-06-10 13:19:24 UTC

Description of problem:

In a cluster, with locking_type set to 3, start clvmd on all nodes, shutdown clvmd on one node:

pvs will fail to scan devices because it cannot obtain cluster locking.

vgs/lvs will instead report the error (correctly) and then provide the information.

Behavior should be consistent across all tools.

Comment 2 RHEL Program Management 2014-03-22 06:46:41 UTC

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

Seems this no longer an issue:
