Hello Varkonyi, Windows clustering requires the use of SCSI 3 clustered persistent reservations, to support this with Ceph you could use our distribution PetaSAN: www.petasan.org which supports this and passes the Windows clustering tests. /Maged On 12/04/2021 10:28, Várkonyi János wrote:

Hi All,

Use anybody windows file server with ceph storage? Finally I can do the gateways. We've a ceph storage with 3 nodes and we can add this to windows via ceph-iscsi. I'd like to use it with 2 windows 2019 servers in failover cluster. I can connect to the storage each sides. But when I check the MPIO device Details all nods are connected and active, I've not "stand by" node. I'm not for sure it is right or it is a problem. I setup up the deatils from the ceph documment. TimeOutValue = 65; LinkDownTime = 25; SRBTimeoutDelta = 15. I try to validate failover cluster configuration and I get an error: "Failure issuing call to Persistent Reservation REGISTER AND IGNORE EXISTING on Test Disk 0 from node FS102.trafficom.hu when the disk has no existing registration. It is expected to succeed. The device is not ready." Did anybody see this error?
