That is correct -- the upstream kernel LIO doesn't have any support for distributing SCSI-3 persistent reservations between iSCSI gateways at this time. SUSE has some custom kernel patches to distribute those reservations via the Ceph cluster but it has been previously rejected from inclusion in the upstream kernel. There is also the PetaSAN project which is derived from the SUSE kernel plus some other changes. > Has anyone managed to get ceph to serve iscsi to windows clustered shared > volumes?
