Mirrored boot SSD showing as unassigned

TrueNAS General

Raising this again a bit more briefly to hopefully get some help identifying what could have gone wrong here.

I just migrated my nvmes to a new pool - no biggie, but I rebooted after as I needed to have a play around with k3s not mounting properly.

After rebooting, I’m seeing one of my two boot-pool devices showing as unassigned in the WebUI.

The device is ata-INTEL_SSDSC2KF240H6L_CVLT646100S0240CGN and the system at least sees it attached and online (although no idea why it’s showing up with this name instead of sdi3).

No alerts, no warnings, no other indication of issues. I tried to detach and reattach but it is just not having it:

root@truenas[~]# zpool detach boot-pool ata-INTEL_SSDSC2KF240H6L_CVLT646100S0240CGN
cannot detach ata-INTEL_SSDSC2KF240H6L_CVLT646100S0240CGN: no such device in pool
root@truenas[~]# zpool detach boot-pool /dev/sdi3
cannot detach /dev/sdi3: no such device in pool
root@truenas[~]#

Any ideas? Last time this happened I had to pull the drive out, detach it while it was missing from the system, then reattach it. Though I’d like to be able to figure out exactly why this is happening.

I feel like this isn’t supposed to look like this.

Got it detached:
