Pool degraded now offline, doesn't show any discs in pool

[sstainba]

I'm relatively new to TrueNAS. One of the pools I had set up was 4x 4TB HGST in a ZFS2 configuration. Yesterday I got an alert that the pool was degraded as one of the disks was offline. It came back after a reboot. However, today the pool went offline and won't come back. The 3 or the 4 disks shows up but it doesn't seem like they're included in the pool any longer. Can this be corrected? I'm building a new pool with 2 new disks tomorrow and I want to bring this one back up long enough to move the data onto the new pool. Should I export/disconnect this pool and then create a new pool and import those disks? Will that let me read the data?

I'm running TrueNAS core 12.0-U2.1

Here is the output of the zpool iport command:

The pool may be active on another system, but can be imported using
the '-f' flag.

Did you try zpool import -f ?

I haven't yet because I wasn't sure if that was the right thing to do. I wasn't sure if I needed to replace the lost disc first or not. (only 3 of the 4 are showing online). I would rather not replace it as I'm just going to create a new pool with new discs.

Why do you say "ZFS2" configuration when your zpool import states "zraid1"? Normally a zraid1 can only have one faulty disk. I would have replaced the disk first and see what happens once you put that bad disk offline and replace?

You're right, I misspoke. Is it normal that the pool would go offline if one of the disks fails? As I mentioned, I'm not to TrueNAS. Before I was using the BIOS RAID w/ Windows Server...
