Rebooting TrueNAS shows UNAVAIL for Disk in ZPool

Looking for a bit of help to understand and possibly solve a problem.

On reboot of TrueNAS, one of my pools sends an alert as follows:

impact: Fault tolerance of the pool may be compromised.
eid: 6
class: statechange
state: UNAVAIL
host: truenas
time: 2024-11-03 12:22:22-0500
vpath: /dev/sdb2
vguid: 0x2AA59DC5D3CF043D
pool: GoldMedia (0x2ABFDEBFF9ABFB79)

This is a ZFS Pool of 3 disks in the vdev + 1 spare.

The other two pools don’t seem to have a problem.

I think this may have stemmed from one of two situations:

  • I added two disks (WD Red) which became a different pool, and may have accidentally rearranged the SAS to SATA connectors on the existing pool Disks (WD Gold)
  • One of the WD Gold Disks was replaced with an RMA due to failure.

The zpool itself looks good in the GUI with no missing disks. From the CLI for easier output:

# zpool status GoldMedia
  pool: GoldMedia
 state: ONLINE
  scan: scrub repaired 0B in 1 days 08:53:05 with 0 errors on Wed Oct 16 13:53:07 2024

        spares
          sdc2      AVAIL

With the GUIDs showing in decimal

 state: ONLINE

2AA59DC5D3CF043D = 3073035793737909309

Which is the sdc spare

What should I look at because I’m just trying to sort out:

  1. Is something wrong? I don’t think so based on what the GUI shows me.
  2. Can I make any changes so that I don’t get the email each time the system reboots (e.g. OS upgrades).
    Let me know what info you might need to help debug … the system runs rather well aside from this, so I haven’t done much other than set it up in the GUI a long time ago (TrueNAS Core) and upgrade to where I am today.

System Info:
Dragonfish-24.04.2.3 (just did this patch update, got the email which reminded me to post)
Intel(R) Core™ i7-10700
32GB RAM
NVMe Drive for the OS on the Motherboard
Broadcom / LSI SAS2308 for the 6 drives (2xWD Red SSD + 4x WD Gold SATA HDD)
2x Intel 82599ES 10-Gigabit for networking
