Subject: [PATCH 13 of 13] LVM: 2 mirrored log monitor fixes
Date: Wed, 17 Feb 2010 11:57:49 -0600 [thread overview]
Message-ID: <201002171757.o1HHvnpB005275@hydrogen.msp.redhat.com> (raw)
Patch name: lvm2-mirrored-log-monitor-fixes.patch
If an event is received on a mirrored LV which also happens to
be the log of a mirror, strip off the '_mlog' component extension
of the name and pass the encapsulating LV to 'lvconvert --repair'.
