Well IET currently doesn't support persistent reservations we do plan on supporting it in the not too distant future.
I want to set up a Windows Server 2008 Cluster using one iSCSI Target with two LUNs. iSCSI initiator successfully connected to my iSCSI-Target server, and the two LUNs appear in Disk Management as expected. Partitioning and formating was successful, too.
When I start Failover Cluster Management and Validate a Configuration the "Validate SCSI-3 Persistent Reservation" fails with the message "Failed to Register PR key for cluster disk 0 from node nodename.fqdn status 1 - Cluster Disk 0 does not support Persistent Reservation".
Looking around a bit it seems that the Linux iSCSI target packages (IET, etc.) do not support SCSI-3 persistent reservations which Windows 2008 needs.
Is this supported and I am just missing something? Or are there any plans to add support anytime in the future?
