[Linux-cluster] Cluster/GFS issue.

[Allgood, John]

Hello All

 

I am having some issues with building an eight node Xen cluster. Let me
give some background first. We have 8 dell PE 1950 with 32GB RAM
connected via dual brocade fiber switchs to an EMC CX-310. The guests
images are being stored on the SAN.  We are using EMC Powerpath to hand
the multipathing. The Operating system is Redhat Advanced Platform 5.2 .
The filesystems on the SAN were created using Conga CLVM/GFS1. We have
the heartbeat on an separate private network. The fence devices are Dell
DRAC's.

 Here is the problem that we are having. We can't on an consistent basic
get the GFS filesystem mounted. On the nodes that don't connect it will
just hang on bootup trying to mount the GFS filesystem. All nodes come
up and join the cluster at this point but only 1 or 2 will completely
come up with the GFS filesystem mounted. If we do an interactive startup
and skip the GFS part all systems will come up on the cluster but
without the gfs mounted.

At this point I am not sure what to do next.  I am thinking it may be a
problem with the way the GFS filesystem was created. We just used the
default settings. The LVM is 668GB created from an RAID10.

 

Best Regards
