system like ceph, but async

[aurelieng2009]

Hi,

I have 3 server to cluster in 3 diffèrent geo location,
I would like to setup a constant réplication process, like ceph, but in a async way,
I have some fast disk but limited bandwith between each host

would it be possible to have something similar to ceph, but with full disk speed even if the replication take longer ?

I'm testing zfs with replication but the fact that we need to input each VM into "replication" 2 time (I want the replication to be on the 3 node) will be source of mistake
and I still need to see in case of power loss if zfs will start the vm elsewhere like ceph with HA

any Idea of what could I setup for this ?

Thanks

DRBD has an async mode and in version 9 supports more than 2 nodes. Linbit also provides a Proxmox plugin to integrate DRBD seamlessly.
