Parity Disk 2 is Disabled

[Uggers]

Hey,

I'm hoping for a bit of assistance, I got an error pop up for my 2nd Parity drive and then it went disabled.

I tried to do a smart test but it wouldn't start.

 

I restarted the box and checked the connections and it seemed ok.

The only changes I've had for a few weeks and today was some new downloads and I moved some ISO's and some of my dockers updated.

Not to say it couldn't be those things but normal things I guess?

 

I've attached my diagnostics and the quick smart test I was able to run after it restart. I'm running a longer smart test now and will add it on if its needed, but its obviously quite slow.

Disk dropped offline, check/replace cables then run a SMART test.

Thanks, I've reseated all the cables and the drive back onto the disk plane.

 

I am now just re-running the extended smart now and will attach results. I thought I'd clicked it last night but I hadn't DOH!

It seems to be ok. So I guess I should re-enable the drive and see how it works.

yes do you know how to proceed?

Would recommend replacing/swapping cables before the re-sync to rule them out if it happens again.

I believe it is;

Disable Array

Un-assign Disk

Re-enable Array

Disable Array

Assign Disk

Re-enable Array - it will then rebuild parity on that drive

Yeah I swapped them over just to make sure.

The correct verbs (which correspond to the buttons in the webUI) are Stop (instead of disable) and Start (instead of re-enable)

Thank you, appreciate the clarification will stop a follow up question

Its about 1 hour away from rebuilding but about 20 minutes in I got

 

Reallocated sector count 412

 

The case I am using is a lian li pc-q25 which has a backplane, so I wonder if maybe that's faulty around that drive.

If I shut down unraid, then swap the parity drives around physically, would it be safe to guess if

 

1. The same drive still has Reallocated sector count issues, the drive is failing (2017 drive)
2. If the other parity drive is now getting Reallocated sector counts, then its likely fault with the backplane on the case (I swapped all SATA cables when I was in the case earlier)

Reallocated sectors will always be internal to the drive in some way.    The only external factor I can think off that might contribute would be borderline power.

Ah fair enough, I thought I had read someone where might be SATA Cables as well

I'm probably just confusing the issues now.

SATA cable problems trigger connection issues which show up as UDMA CRC errors at the SMART level.
