[Linux-cluster] scsi reservation issue with GFS

[Ryan O'Hara]

Can you dump the registered keys and reservation key?

# get a list of keys resgitered for a device
sg_persist -i -k <device>

# tells you which key holding the reservation
sg_persist -i -r <device>

It appears that this node is trying to access /dev/sda but is not
registered with the device. WERO reservations will only allow
resgistered nodes to write to the disk.

Is this RHEL4? RHEL5?
