Greetings all, I have 2 vmware esx servers, each hitting a NetApp over FS, and each with 3 RHCS cluster nodes trying to mount a gfs volume. All of the nodes (1,2,& 3) on esx-01 can mount the volume fine, but none of the nodes in the second esx box can mount the gfs volume at all, and I get the following error in dmesg:
Are you intentionally trying to use scsi reservations as a fence method? It sounds like the nodes on esx-01 are creating reservations, but the nodes on the second esx box are not registering with the device and therefore are unable to mount the filesystem. Creation of reservations and registrations is handled by the scsi_reserve init script, which should be run at startup on all nodes in the cluster. You can check to see what devices a node is registered for before you mount the filesystem by doing /etc/init.d/scsi_reservce status. If your nodes are not registered with the device and a reservation exists then you won't be able to mount.
