> There is no option to replicate a full ZFS pool to another. not exactly what i want to do. my bad in saying "full replication." what i meant was all vms are replicated. on other nodes.
i was thinking that each node could have one pool for primary vm images and a second to receive replication from other nodes. > So, you have a current pool with one raidz2 VDEV made up of 4x 2TB > disks. yup > Because if you have another set of 4x 2TB disks, you can just expand > the pool with another raidz2 VDEV, without expanding the current VDEV > you have. yup. what are the performance implications? > If you add another VDEV, the pool could have the following layout: > > pool > raidz2-0 > disk0 > disk1 > disk2 > disk3 > raidz2-1 > disk4 > disk5 > disk6 > disk7 yup > If you want to create a new pool, then things will be a bit more > complicated, as you would need to create a new storage config for it > as well, Move-Disk all the disks over to it.
