I know this isn't the right group for this, but I am hoping someone can point
me in the right direction.
I have set up a DRBD cluster for replicating a drbd volume across two servers.
Each server has its own IP address (10.89.99.31 and 10.89.99.32). I also have a
collocated IP address (10.89.99.30) used for mounting the volume on other
computers. I am using cman and pacemaker.
I can mount the volume with no issues using 10.89.99.30. When I unplug the
network cable from my second storage server, the computer will lose
connectivity to the NFS share, even though the IP address shows it is shared. I
can still ping 10.89.99.30, but I can't find the share using
showmount -e 10.89.99.30
I have attached the cib.xml and cluster.conf files from my drbd cluster. I know
this is more of a pacemaker issue, but maybe someone here has experience with
this?
