Hi Josh,

My cluster nodes are on the local mirrored disks, I have several other
VMs that do not participate in the cluster, and they are located in a
VMFS on the shared storage.

Each cluster node has three disks:
sda* : the operating sys and it is local to the host
sdb1 : a 20MB quorum disk on netapp (which mounts fine from all nodes)
sdc1 : a 600GB gfs volume on netapp (only mounts on 3 nodes from first
host)

both the quorum and the gfs use RDMs (one each per host)
the rdms were created on nodes 1 and 4, and then nodes 2 & 3 mount the
existing rdms from node 1, and 5 & 6 mount the existing rdms from node
4.

Each disk has it's own virtual scsi controller.
sda has scsi controller set to none.
sdb and sdc have scsi controller set to physical.


The error I get when attempting to mount from nodes 4,5, & 6 is:

mount: /dev/sdc1: can't read superblock



Any help at all would be great.


Thanks,
-C
