Hello,

 

Woke up to a disabled disk today, having trouble deciphering exactly what's going wrong.  Diagnostics attached.

 

• I had some read errors a few months ago on both older drives (disk2 and disk4, both 6TB drives, both older 4-5 yrs old) but smart looked fine on both, so I continued running. 
• Server is getting older, built in 2014.
• Parity check started yesterday but didn't finish due to disk2 failure. 
• disk2 failure happened late in the parity check and this drive likely wasn't doing anything at that point, as it's 1/2 the size of parity.
• I'm seeing recurring out of memory errors happening between 3-4am each day, along with Plex being killed each time.

 

I can't really make sense of what's going on, clearly more than just a failed drive.  Maybe someone can help? Should I run memtest?

 

I don't have a spare disk at the moment, but I can copy the data to another disk in the array and remove the failed disk, or copy it off the array if that's safer.

 

Thanks!

Looks more like a power/connection issue, but since the disk dropped offline there's no SMART report, check/replace cables and post new diags after the disk comes back online.

Hello, thank you for the response.  I checked and re-set the drive connectors and did a hard reboot to see if it would come back.  I could hear a drive doing a click / click / click routine, and now it's showing disk2 as not installed.  I'm thinking it's completely toast?  I'm going to start moving the data off that drive in preparation for removal.

I would recommend replacing/swapping cables and If it's still making weird noises and not coming back online replace.
