Greetings, Glusterites -
I have a suboptimal situation, and am wondering if there is any way to create a replica-3 distributed/replicated volume with three machines. I saw in the docs that the create command will fail with multiple bricks on the same peer; is there a way around that/some other way to achieve this?
The reason for this terrible idea is entirely about deadlines interacting with reality. I need to go into production with a new volume I’d really like to be D/R before additional machines arrive.
You can use the force option at the end of the `volume create` command
to make it work for whatever brick placement strategy you wish but since
you anyway have 3 machines, there shouldn't be a need to do that. The
following layout should work:
Node1 Node2 Node3
-------- --------- ---------
B1 B1' B1" <----------3 bricks of a replica subvol
B2 B2' B2"
B3 B3' B3"
and so on. `Volume create` would complain only when you try to place
bricks of the same replica subvol on the same node.
Hope that helps,
Ravi
Thanks,
