Hello, yes, U're right, but only as separate domain ( ? ( mirror realized by any clever storage on background ) , but if mirror needed over two locations ? I had an idea realize mirror over two loacation via gluster ( with iscsi  bricks ) Pa. On 1/18/24 09:21, Strahil Nikolov wrote:

I’m not sure if I correctly understood your intention, you want to use 2 nodes for a 3 node deployment, is that what you want to do? The replica 3 arbiter 1 means you need 3 nodes, 2 nodes will have data, and 1 node will have the checksum only (the arbiter). On oVirt, 3 nodes is mandatory as minimum.

Something like this: gluster volume create TEST replica 3 arbiter 1 <location-one-host1 - iSCSI target > <location-two-host2 - iSCSI target> < location-three-host3 - /dev/sda5 e.g. > - ALL applied on multinode ovirt cluster thx a lot for any help regs.
