Hello folkz,
I have two nodes with DRBD configured as dual primary for node1 and node2.
/dev/drbd0 block formatted as OCFS2 and mounted as /data on the both nodes.
I had a raid failure on the node1 and immediately ocfs2 /data mount on the
node2 became unavailable and shortly thereafter node2 went into reboot.
I wonder if this an is expected behavior of OCFS2 or I missed something in
/etc/drbd.conf or /etc/ocfs2/cluster.conf
Please take a look at my config files below.
Thank you in advance,
Alex
