Parity disk red - unRAID 5.0 Beta 10 (screenshot and smart results included)


Recommended Posts

Greetings,

 

I am new to unraid and servers in general, but so far I have enjoyed using unraid for my storage needs.  I have had my server running for about one month. Here is the issue I am having:

 

1. Last week the Parity drive showed up as a red dot.  

 

2. Yesterday I performed the "trust my array" function and it attempted to fix the parity drive.

 

3. Right after finishing the full parity sync (which took several hours), the drive again had a red dot next to it.

 

4. I have opened the case and verified that all cables are installed correctly.  After the drive fails and I take the array down, it displays the message "new parity disk installed" as if it did not know it was there. 

 

Screenshot located here: http://i.imgur.com/JjZgh.png

 

Any and all help is greatly appreciated.

 

Thanks!

If it is "red"then writes to it are failing.  That is not good, as it pretty much says your parity disk is not going to be correct if you try to re-construct another drive.

 

There are 26 unreadable sectors, waiting for when they are next written.

 

 

I'd have look in the syslog for other clues.  It could be power related, or the disk could be heat or vibration sensitive.

So I think I am going to give up on this whole unraid thing.

 

Not only does the parity drive not work, but now my other drives are failing also.

 

I've had computers my whole life running all versions of windows and I've never had a hard drive fail on me.  I thought, at a minimum, unraid would give me that level of stability. 

 

Currently my unraid machine is booting incredibly slow.  It's freezing up. The only disk to seem stable up to this point has now shown up as "unformatted".  Right now I can't access the tower menu at all.  I restart only for it to freeze up and crash again. 

 

I hate to say this, but I give up.

Your hard drive is bad. Now, was it bad from the factory, did it suffer during the shipping - we do not know.

 

But there is one thing that we DO know - you are probably using inadequate power supply as a starter. And you did not provide any other hardware info to see if you are using other troublemaker parts.

 

This hard drive has been on for around 784 hours and this is in line with your statement for one month use (784 hours are 32 days and a change). However in that time your HD has also 742 start/stop operations and 703 power cycles - so it has been shutting down and powering back up on every hour - and this is not the typical Unraid pattern.

During this time it also shows raw values for the offline uncorrectable sectors, current pending sectors and multi zone error rate - so whatever bad power supply or old, used, worn out cables (and especially loose Molex connectors) something in your system is killing your hard drive(s).

 

Good luck

Thanks for the diagnosis.  I probably should have mentioned the hardware.

 

I'm using a Corsair CX430 power supply. All of the components were recommended specifically for an unraid build and were purchased brand new.  All of the cables are brand new and plugged in snugly.

Here is a link to a post I made detailing the build http://forum.xbmc.org/showthread.php?t=107969&highlight=hybridsole%27s

 

I also don't understand how in the first month of usage, I never noticed the system going down other than during a power outage.  And that happened maybe 2 or 3 times.  The drives would spin down, yeah, but they would come back up the moment I needed to access a file.  The system remained up and running for the majority of that month and I don't remember any issues up until this parity drive started causing problems.

 

Now, it seems, everything else has started going haywire.

Bump.  So, where do I go from here?  Currently the system isn't recognizing any of my hard drives.  When I reboot it will sometimes see one, two, or all three drives.

 

Is this a bad power supply?  Bad hard drive power cords?  Bad sata cables?  I just don't get it.  They are all brand new and (seemingly) worked so well for the past month.  Now I can't see any of my hard drives.....

 

Please help.

Start with a memory test.  Then, isolate.  Try booting with 1 drive.  Does the BIOS see it, consistently? , then try two drives, etc...  No need to start the array, just see if the disks are present...
