Hello,
so far as I understand I can use fence_scsi on a two node cluster, if the fence
running on one cluster the other cluster has no access to this devices,
correct? I've a 2node cluster with shared JBODs and configure fence_scsi, but I
still can use/mount all this devices on both nodes. Did I something wrong?
