[Linux-cluster] SCSI reservation conflicts after update

[Sajesh Singh]

After updating my GFS cluster to the latest packages (as of 3/28/08) on 
an Enterprise Linux 4.6 cluster (kernel version 2.6.9-67.0.7.ELsmp)  I 
am receiving scsi reservation errors whenever the nodes are rebooted. 
The node is then subsequently rebooted at varying intervals without any 
intervention. I have tried to disable the scsi_reserve script from 
startup, but it does not seem to have any effect. I have also tried to 
use the sg_persist command to clear all reservations with the -C option 
to no avail. I first noticed something was wrong when the 2nd node of 
the 2 node cluster was being updated. That was the first sign of the 
scsi reservation errors on the console.

 From my understanding persistent SCSI reservations are only needed if I 
am using the fence_scsi module.

I would appreciate any guidance.
