gluster on iSCSI devices in ovirt environment
hello dears, can anybody explain me HOWTO realize 2 nodes + aribiter gluster from two (three) locations on block iSCSI devices ? 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. Pa.
Hi, Why would you do that?Ovirt already supports iSCSI.

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:

In such case, use iscsiadm to mount the lun (man iscsiadm has good examples) and follow standard gluster setup.Keep in mind that you might have reduced performance as your bandwidth will be shared between iscsi and gluster (in case you use the same bond).

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.
