January 6, 20242 yr I have 1 4tb cache drive formatted xfs. I added a second drive and tried adding it to the pool and ended up with "Unmountable, no file system". After removing the 2nd drive and running a repair I was able to get things back to the original state. Now I'm hesitant to try again, I don't know if I did something wrong. Before attempting again, do I want to stay XFS? Or should I use this as an opportunity to move my cache to ZFS and how do I do that? Does it matter? Using the existing xfs or zfs, how do I properly add a second drive without getting the "Unmountable" error again?

January 6, 20242 yr Author Ah, so that's what broke it then. Thanks. I just found SpaceInvaders video on doing exactly this. Running mover now to get everything off cache. You'd think I'd have known better and looked into it first but nah, I'm a "What's this button do" type person and try things first, lol. thanks
