[Linux-cluster] scsi reservation issue



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:

Does anyone have a clue as to where I should start looking?


Thanks,
