drbd resource is not getting promoted
|
|
Hello all,
I have two nodes cluster CentOS 5.4, self compiled drbd-8.3.5-3 against
kernel 2.6.18-164.6.1.el5.
The cluster runs drbd resources in primary/primary
However always on tweety1, drbd2 (almost all of the times) and drbd0&1
(some times) the resources do not get promoted.
following are kernel messages on tweety1 for the last event related to
r2:
block drbd2: Starting worker thread (from cqueue/0 [183])

'drbdadm primary r2', promotes the resource to primary without problem.
Am I doing something wrong?
Thank you All for any help.
