I installed Proxmox 4 on a 120GB SSD. I then created a 4TB software raid 1 partition on 3 enterprise sata drives as /dev/md0 and formatted with ext4.

I then altered fstab.

I commented out


#/dev/pve/data /var/lib/vz ext3 defaults 0 1


Added


/dev/md0 /var/lib/vz ext4 defaults 0 0

Should this all work ok or will there be any issues? I plan on LXC containers mostly.
 
Say I have a Server with four 4TB drives. I want to use one for backups and the other 3 in a raid1 array for my containers. How would I set that up on Proxmox with ZFS? Totally new to ZFS but have used linux software RAID before.
 
Raid 1 requires pairs of drives aka mirror. The ZFS link posted above by Dietmar covers how to do a raid 1.
 
With mdadm I have had 3 drives in a raid 1 array. Is there any reason I cannot do this with ZFS?
 
You can mirror as many drives as you like with ZFS mirror. Honestly, though, I think having the "backup" on the same machine as the original data doesn't seem much of a backup. Instead of the mirror I'd consider a raid-z1 so that the reads and writes are distributed more evenly.
