I need a disk storage block that is shared between two Windows servers.

Some storage devices require specific firmware versions or settings to function properly with failover clusters. Please contact your storage administrator or storage vendor to check the configuration of the storage to allow it to function properly with failover clusters" how can i resolve this ? Is there a solution to this issue?
Yes, use iSCSI, and a Windows fail-over cluster (with a witness disk). We have MSSQL fail-over cluster running this way. You can use LIO (targetcli) with krbd or rbd-nbd as storage backend for LIO. That's what we use in a home grown cluster with CTDB: ceph for storage and split brain prevention. But nowadays Ceph comes with iSCSI gateway support with HA. See https://docs.ceph.com/en/quincy/rbd/iscsi-overview/
I believe this also supports persistent SCSI reservations. Gr. Stefan _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
