OK. Here we are months later. I sent the failed SSD to a data recovery specialist and got all the missing data. So it would seem that I had cache preferred for the missing files. Then I sent the drive to the manufacture for RMA and got a new one. Now I have the NAS back together and running. Attached are the diagnostics At this point, I just need to rebuild the system, right? Thanks! nasmar-diagnostics-20230413-1600.zip

So the current share that I created, N----r, is not the original share that is missing. In an act of desperation I recreated the original missing share that went by the same name. It had various documents, pictures, and videos on it. That is what is missing. So I cannot say for sure that it had the setting listed above. I guess I will pull drives and run data recovery on them. Then try to rebuild the system. I will also try to RMA the original cache SSD.

How frequently does the mover work? The last set of data was added to the NAS weeks before this failure. Does the mover work on a timetable or a size threshold?

My BIOS is up to date, but I did a reflash anyways. Still showing the ACPI errors. Should I try to pull data off the disks with a recovery tool before rebuilding? Though there is not much data on the disks, I cannot loose what is on them. Currently the share that had all my data is not present. Will rebuilding the disks delete my data since the share is not there and not populating the files? nasmar-diagnostics-20230130-1625.zip

The drives are mostly empty at this point. So the low file size is expected. What would you recommend as the next step? Should I attempt to get a new SSD to replace original cache drive or do I still need to sort the ACPI errors? Thanks!

No, I do not have backups. I had made the assumption that a backup would not be necessary with dual parity drives.

All the array and parity disks are present and connected in the machine. Drive 1 is the unassigned device ending in 70MW. The SSD connected now is not the original cache SSD. I have put in a new SSD where the unmountable drive was to test if that cleared things up. I am still not sure if the drive is the issue or the motherboard or some setting in the bios. Thanks!

Here are the diagnostics after the array was started. Thank you for your patience and help! nasmar-diagnostics-20230130-0756.zip

Well the array is not started now since drive 2 is disabled now along with drive 1. I think this happened when the computer was booted with a loose sata cable on drive 2. Drive 2 has a warning stating udma crc error count is 16. I don't know why drive 1 is disabled, but has been since the start of the issue. Is it safe to add drive 1 and 2 back to the array at this point? I don't want to loose the data on the array.

I have tried new SATA and power cables. I have swapped drive positions. It seemed like the ATA errors were following the cache drive. An IT friend took a look at the cache drive and said it may be corrupted, but looked functional. We did not attempt to format it yet since I am not sure what data exists on it. He had a spare 850 Evo SSD. I installed that in place of the original cache drive. I have attached the diagnostics with this configuration. It seems like the ATA errors are gone, but now I see ACPI errors. Can you help me determine the next steps? Thanks! nasmar-diagnostics-20230129-1549.zip

Attached. Thanks! nasmar-diagnostics-20230124-0738.zip

I tried swapping both the power cable and the socket it is plugged into on the PSU. I swapped some more SATA cables. The cache still shows Unmountable: Wrong or no file system. My Disk 1 that was disabled now shows not installed, but available as an unassigned device. What should my next steps be? Thanks!

I did replace the sata cable on the cache drive. I made sure all the other cables were seated well. Should I try swapping more of the sata cables? I forgot to mention in the original post that I have been having issues with the system shutting down on its own after about a week of up time. When it does this, I have to switch off the power supply for about thirty seconds and then the system will power back on. I have already replaced the power supply. Again, thank you for your help!

My cache SSD says it is Unmountable: Wrong or no file system. The shares are also gone and not accessible. This occurred after I had to reset the web GUI root password by deleting a couple files (smbpasswd and shadow). I have tried to re-seat and swap the SATA cable, but this has not corrected the issue. The Check Filesystem Status came back with Csum mismatches, bad tree block, owner ref check failed, bytenr mismatch, and unresolved ref dir. I also tried recreating the missing share, but this has not restored the files. Attached is the diagnostic report. Can anyone offer advice on how to get my files back and system running again? I am a novice with with Unraid, so even basic issues may be at fault here. Thanks for your help! nasmar-diagnostics-20230123-0928.zip
