OS: SUSE Linux Enterprise 11 SP1
HAE SP1
drbd version: 8.7.3
on one node I got the following messages while starting the drbd daemon
node1:~ # /etc/init.d/drbd start
Starting DRBD resources: [ d(r0) 0: Failure: (114) Lower device is
already claimed. This usually means it is mounted.
[r0] cmd /sbin/drbdsetup 0 disk /dev/sdb1 /dev/sdb1 internal
--set-defaults --create-device failed - continuing!
s(r0) n(r0) ].
stop/start the drbd daemon two times in a row fix the issue, i.e no more
such messages.
and the above message never comes before today.
likewise the above message didn't came on the other node(node2)
cat /etc/drbd.conf
include "drbd.d/global_common.conf";
include "drbd.d/*.res";
cat /etc/drbd.d/r0.res
