Wrong SSD total size after upgrade to 6.12.0

[J1mm1]

Hi Everyone, 

 

I'm posting a new thread as i wasn't able to find something identical to my situation.

 

I have an array composed by 5 discs:

 

2x 2TB HHD as parity discs

1x 2TB HHD (identical to the parity discs) as main array disc

2x 480GB SSD (disk 2 and 3)

 

Everything was working fine until the update to Unraid 6.12.0, right after the reboot both 480GB ssd have started to be seen with a total size of 1GB each, causing of course a mismatch between the expected size and the detected size.

 

I've tried removing the SSDs from the array and restarting it, they add them back but nothing changed.

 

What options do I have? Should I format the disks and restore from parity? Is there a reason why this might have happened and a way I could prevent it in the future?

Thank you all.

You should post your system's diagnostics zip file in your next post in this thread to get more informed feedback.  It is always a good idea to post this if your question might involve us seeing how you have things set up or to look at recent logs.

Diagnostics attached. Sorry for not doing it in the first post.

 

Thanks

Looks like an SSD problem, for both, SMART reports are incomplete, update would be a coincidence, since SSDs usually fail on reboot/power cycle, you can try swapping cables with different devices to rule that out, and if the same they will need to be replaced.

Thank you, I did what you've suggested with no success.

I don't understand how the SSD could be damaged though, they are new units with maybe 1 month of power on life and very low stress on Unraid.

 

Hopefully new units I'm going to use as replacement won't fail as fast.

Just for the record. I've been able to fix the issue by doing a security-erase with hdparm. I don't think it actually did anything physically as the process was immediate but the disks size has been restored and I've been able to rebuild the array.

 

No SMART errors on both disks so I don't know exactly what happened but now it's fixed...

 

Thank you
