Hi. No worries it was a firewall
issue. Not quite as bad as I though J . Greg Machin From: centos-bounces@xxxxxxxxxx
[mailto:centos-bounces@xxxxxxxxxx] On Behalf Of Machin, Greg Hi. The short story... Rush job, never done clustered file
systems before, vlan didn’t support multicast. Thus I ended up with drbd
working ok between the two servers but cman / gfs2 not working, resulting in
what was meant to be a drbd primary/primary cluster being a primary/secondary
cluster until the vlan could be fixed with gfs only mounted on the one server.
I got the single server working and left to for the contractor to do there bit.
Two months down the line and a few other hiccups in the mix I have a server
that wont mount the gfs partition.. assuming that drbd hasn’t gotten confused
and lost the data on the drive.. If I can how do I fix this. Drbd is currently as follows: [root@mcvpsam01 init.d]# drbd-overview 1:r0 WFConnection Primary/Unknown
