Sadek, Abdel napisał(a): > Are the SCSI-3 reservations used by RedHat native cluster for scsi > fencing single threaded or multithreaded? Hello, In RHCS SCSI-3 reservations fencing is done via two scripts. Bash /etc/rc.d/init.d/scsi_reserve startup script and perl /sbin/fence_scsi. Why You need to know if it is single or multithreaded? Here preformance isn't the problem. Best Regards Maciej Bogucki -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
