Installed Proxmox yesterday on 2 x 120GB SSDs ZFS(RAID1) and booted fine. Cleared the config and recreated it today and am getting the following error. Is the issue with the drives or HBA?
What do you mean by "cleared the config"? Sounds like you got two ZFS pools both named "rpool" nd ZFS doesn't like it. If you reinstalled PVE, did you wipe both SSDs before so there is nothing of the old pool remaining?
