Ok, I also am going to use Proxmox. Any advise on how to configure the
bricks?
I plan to have a 2 node replica. Would appreciate you sharing your
full setup :-)
Three node replica - preferred to two as quorum works best with a odd
number of nodes. If storage on a third node is an issue then use an
arbiter node.

I use sharding with 65MB shards, it makes for very fast efficient heals.
Just one brick per node, but each brick is 4 disks in ZFS Raid 10 with a
fast SSD log device.
