[6.9.2] Help understanding SMART report

[Bilal Yassine]

Hi 

i woke yesterday to find one of my drives (disk 2) disabled by the OS. 

 

I have 2 parity drives so i'm not too concerned about losing everything right now. I disabled docker and VMs and have disabled network access to the server except from my PC (just to be safe and not aggravate the problem) 

 

I ran extended SMART on the drive which took more than 12 hours. the report shows 0 reallocated sectors but i don't know what else to look for to try and understand why this happened. 

 

report attached.

 

Thanks in advance for the help and assistance.

Your diagnostics might provide more details on why the disk was disabled if you did not reboot.

hi thanks for the reply. 

 

I had done a reboot a little earlier but i haven't since i saw the drive became disabled. so i'm not sure if it happened before or after reboot. 

 

attached is anonymised diagnostics.

It happened before the reboot so we can't see what the problem was, disk looks fine and the emulated disk is mounting, so you can rebuild on top, I would recommend replacing/swapping cables on disk2 before rebuilding to rule that out if it happens again.

thank you for the advice. i will replace the cable and rebuild. thanks again.
