Hi, initially submitted here:
https://bugzilla.redhat.com/show_bug.cgi?id=1442593
The node that crashed was at the time the active member of an
active/passive Pacemaker cluster, using DRBD backed replicated storage
for iSCSI and NFS resources.
The RedHat developer closed the bug due to loading drbd out-of-tree. The
module is built using the source from http://git.drbd.org/drbd-8.4.git/
Even though it may or may not be related to DRBD, I thought it's worth
having your opinion on this.
More details below.
