<br>
I have 2 servers running about 10 OpenVZ containers and 4 KVM VMs, using<br>
Proxmox as a frontend.<br>
<br>
Both servers have 1TB hdds, mirrored using zfs.<br>
<br>
I'm considering adding high availability to this setup.<br>
<br>
My idea: configure a third server as a backup and use DRBD to mirror the<br>
data from both servers over the network.<br>
<br>
Most guides I've seen on the Internet assume you're going to use full<br>
disks for DRBD mirrors.<br>
<br>
In this case, I would create a partition on each server (200-300 GB) and<br>
use DRBD to constantly mirror data on the third server.<br>
<br>
Is this setup possible? The third server would have 2 different DRBD<br>
partitions.<br>
<br>
What do you recommend running on top of the DRDB partitions? ext4?<br>
<br>
Thank you.<br>
<br>
Best regards,<br>
Dan<br>
