Hello

I am fairly new to Unraid and I have so found it to be a bit hit and miss as far as storage systems go.

It seems to fail drives on regular basis.

Firstly my 5TB drive failed in parity. then I replaced that with a pair of 6TB Ironwolf Pro drives. Been running for about 1 month now and I have just noticed both Parity drives disabled.

How do you spin up or un-disable a drive.

I can't believe both of these drives have failed.

All my other Ironwolf drives in the array are perfect.

 

So question is, with both drives currently disabled, how do I enable them to recheck them. 

And why would this continue to happen

A strange one indeed

hopefully someone can assist. otherwise I may have to go back to Freenas, where it is free, and I never had these issues with the drives

Bad connections are much more common than bad disks. Probably nothing wrong with any of the disks including the one you replaced. You should have asked for help sooner. 

 

Go to Tools-Diagnostics and attach the complete Diagnostics ZIP file to your NEXT post in this thread. 

Thanks for the quick reply.

Yes I prob should have posted sooner, but first time I was using normal drives for parity.

This time with the ironwolf drives, I am concerned.

Attached is the file you requested.

I just noticed after a reboot of the unraid server that one of the parity drives is now missing and not attached.

And the second one is still disabled.

I will check the connections again and see what is going on,

Sorry I wasn't able to respond sooner.

 

syslog indicates problems communicating with multiple disks so also check controller and power connections, including splitters.

 

Unraid disables a disk when a write to it fails. Any write to the parity array also writes parity at the same time. When a write to any disk in the parity array fails it is disabled because it is out-of-sync and so needs to be rebuilt.

 

After you get parity connected again post new diagnostics.

Ok so I was able to spin the unit down yesterday and remove the 4 port Sata card. It would seem that the heatsink covering the 2 small Ic units had come loos somehow and I would hazard a guess that the card was overheating causing the issues.

I have repasted the card, and changed the ports that the drives are connected to.

On reboot I am able to re assign the one drive that was missing. The other drive that was disabled is still disabled. so I will need to remove it.  reboot and re-assign it to a slot for parity.

Hopefully this will fix the issue.  I will keep an eye on the controller. and will order a new one to replace it. as once burnt, twice shy .

Many thanks for the assistance on this. Is muchly appreciated for a newbie

now I have to wait about 4 days for one drive to parity rebuild then assign and do the same with the second to find out if all is good

That seems like a really long time for only 6TB. I usually estimate 2-3 hours per TB.

yes. I agree. I think it started at 4 days. now it is down to another 22 hours. It has reached 25% in 7 hours today. Still seems too long for parity check. and then I have another one to do aftr this one..I hope the sata card holds up until a new one gets here
