I randomly logged into my new TrueNAS build as I have yet to finish setting up my email server and getting notifications set up in TrueNAS and saw this error:
Pool DataPool01 state is DEGRADED: One or more devices could not be opened. Sufficient replicas exist for the pool to continue functioning in a degraded state. The following devices are not healthy Disk 5543375440076347745 is UNAVAIL.
The system is an older Intel(R) Core(TM) i3-3220 CPU @ 3.30GHz with the maximum ram allowed for that board at 16GB with 24 new 4TB Seagate Ironwolf NAS drives attached to it in a Norco 4224 case. A new EVGA Supernova 850-watt power supply was installed for the system, and it is booting off of mirrored boot drives.
I have the pool set up in 4 VDEVs of 6 disks with RAID-Z2 for each VDEV. The Norco backplanes are connected via SAS cables to a SAS expander an HP 468405-002 which is then connected via dual SAS cables to an HBA card which is an IBM M1015.
When I first built the machine and was making sure everything was working and compatible, I did have some issues with the original SAS cables I got not working and some drives not showing but those have been replaced. Since then I only had one drive (different serial number) not show up once before and a reboot corrected the error until today.
I did use my drive layout chart and the information under the Pool tile on the main TrueNAS screen to identify the drive's serial number and location. I removed it from the bay with the system off and reinserted it to see if it was somehow not seated properly but that made no change. Then I turned the system off again and swapped 2 drives in the same VDEV to see if it could be an issue with the backplane (though other drives on that backplane have no issues) and it did not make a difference.
I also did perform a smart test on the disk. Using my desktop and an HDD dock and it reported no errors. In TrueNAS, I cannot see the drive at all though I am seeing the power and activity lights when the system boots and then just a power light after that. I then put things back to their original.
I am not sure what my next steps are and how to go about resolving this issue. I don't have a spare drive or I would have tried offlining this drive and replacing it. The drives are less than a month old and were bought locally through a reputable reseller all at the same time.
Hopefully, the TrueNAS community can help guide me to the correct way to fix and resolve this issue and if I have left out any details or information that is missing let me know and I will get the information that is missing and post a reply with the details.
