My Unraid Server seems to be crashing


Recommended Posts

Hello,

 

I apologize if I'm posting in the wrong section. Last week my server started to run very slowly:

1. Accessing files from two separate computers was extremely laggy and seemed to take an uncharacteristically long time. Additionally, my weekly parity-check was taking 10x times longer than normal (~2Mbs down from ~120Mbs). 

2. I already tried to swap out power cables and SATA connectors. 

3. I ran a SMART extended self-test in safe mode, for both Disk1 and my Parity. The Parity Completed without error.

4. Disk1 "Last SMART test result: Errors occurred - Check SMART report."

 

WD Red 4TB NAS Hard Drive - 5400 RPM Class SATA 6 Gb/s 64MB Cache 3.5 Inch - WD40EFRX

 

I've included the SMART report. I further apologize if I'm not giving you the appropriate amount of information... I'm very inexperienced when it comes to servers. Thank you SO much for any help you can provide. I've lost many hours trying to trouble shoot this server and am not getting anywhere.

Your description doesn't sound like what is usually meant when someone says "crash".

Instead of SMART report, post Diagnostics (Tools - Diagnostics). It includes SMART for all attached disks, syslog, many other details about your hardware and configuration that give a much more complete understanding of your situation so we can make better informed recommendations.

Constructor - thanks for the swift response and willingness to help.

Sorry about the misnomer... I wasn't sure how to succinctly describe that a drive (or both... or some other hardware related issue) was seemingly failing. 

 

I've attached the diagnostic.

Newbie 😉 - your welcome

 

Based on the failed extended SMART test for disk1 you should replace disk1. Unfortunately, it looks like parity was replaced (by same disk?) and now it considers parity to be a new disk and is waiting for you to rebuild parity. But you need to instead rebuild disk1 onto a new disk.

 

Does that accurately describe your situation? If so it will require some trickery to get Unraid to rebuild disk1 from that parity, assuming it is even valid.

 

Is there any important data on disk1?

Since you have only 1 data disk parity is effectively a mirror so if that parity is indeed valid it would be possible to recover the data directly from parity instead of bothering with a rebuild of disk1 to a new disk.

 

In any case, let us know if I have anything wrong or tell us more details about what you have done.

 

And wait for further advice before doing anything.

While troubleshooting, I removed the Parity and for whatever reason when I reconnected it, Disk1 tried to rewrite. I'm sure it was user error. Therefore, to my knowledge, the Parity drive is completely wiped... which sucks because Disk1, with the data, is so slow that it'd take >1 month to rebuild.

 

Thankfully, I backed up the server's contents to a completely separate external HDD. Sounds like disk1 is trash - hopefully WD will replace it under warranty.
