[SOLVED] Install Proxmox to SSD and then add another SSD for RAID-1 later?

[verulian]

I have a server I've installed Proxmox onto that has one SSD for the main system installation. I'd like to add an identical drive in a month to mirror my base install as a software RAID-1 (raidz maybe?) so I don't have any down time for when the primary SSD fails.

Can this be done, and if so, how?

This looks like it may have the answer, but has anything changed in this regard for Proxmox 7 since this posting?:

Which solution are you referring to? The only software raid that Proxmox supports natively is zfs. Did you install with zfs or did you choose lvm? In the latter case you're probably easier off with a reinstall.

I installed with ZFS on a single SSD. It would be nice to avoid a reinstall for sure.

Seems like it is possible to create a mirror out of a single disk.

Oh nice find @ph0x, thank you. I was having a hard time isolating something like that based on having the right search terms.

I had a hard time getting the server to respond for some reason so I got an archive: https://archive.is/dz0QV
