Woke up this morning to find that my Parity drive has been disabled.  I have attached a screen shot

 

My system specs are as follows

 

 

Model: N/A

System: ASRock - 990FX Extreme9

CPU: AMD FX-8350 Eight-Core @ 4 GHz

Cache: 384 kB, 8192 kB, 8192 kB

Memory: 16384 MB (max. 32 GB)

Network: eth0: 1000Mb/s - Full Duplex

Kernel: Linux 3.17.4-unRAID x86_64

OpenSSL: 1.0.1j

 

The only thing I have found on how I might be able to resolve this was in the link below

 

http://lime-technology.com/wiki/index.php/Make_unRAID_Trust_the_Parity_Drive,_Avoid_Rebuilding_Parity_Unnecessarily

 

Any help would be great

 

thank you

 

 

 

 

Since you don't have any reason to believe your parity is valid, that link is not the way to go. unRAID says it's invalid for a reason.

 

In fact, you don't actually have a parity drive as far as unRAID is concerned, because it has disabled it, probably due to a failure writing to that drive. Any writes to the array are not updating parity since it is disabled, so any additional writes to the array will mean that the parity disk is even further out-of-sync. If you get that drive working again, you will definitely need to update parity.

 

Post a syslog and a smart report of that drive.

Sorry I posted this in the unRAID V5 forum and it should have be in V6 I have recreated it in the connect forum.

I stopped the array so I cannot get a smart report for the parity drive. 

 

I guess the question is do I need to get a new drive (this one is less than a month old) or do I enable it and I have no problem re-running a parity check.

See here for getting smart report and here for syslog.

 

Can't advise on whether to get a new drive without these. We need to know why it was disabled. Maybe the drive, maybe something else.

When I try to run the smart report command I get the following

 

smartctl -t short /dev/sdk

smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.17.4-unRAID] (local build)

Short INQUIRY response, skip product id

A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options.

 

 

As for the syslog the last 100 line are all from 01/10/2015 nothing newer.  And from the looks of things the drive was disabled at around 614 this morning.

How did you get this syslog? I'm pretty sure stopping the array as you said you did should result in syslog entries.

 

How did you determine the drive was disabled around 614 this morning?

I putty'ed into the system and

 

cat /var/log/syslog

 

On the image I posted the first box on the right sees 6:14am.  Also I have the notifications setup and I received an e-mail at:615am saying

 

Event: unRAID Parity disk SMART failure

Subject: Alert: Parity disk failed SMART health check

Description: HGST_HMS5C4040ALE640_PL2331LAGUHAUJ (sdk)

Importance: alert

 

Well, the usual advise is to replace the drive, and then see if you can get the old drive to pass a preclear before you try to use it again. I was just trying to make sure you didn't have a loose connection or something.

I was thinkinthe same thing that a connector might not be connected properly.  I will get another drive and see what I can do. when I get home and am able to physicaly look at the machine.

 

I really appricate all the help as always everyone here is very helpful.

 

Thank you
