Should be obvious from the title but yeah, one of my drives just failed. And that happens to be the parity drive.

 

I was working on my computer this morning when I heard a lot of sharp 'clicks' coming from the server. The server is located below the computer, and just as I finished typing up my document a lot of errors came out via Pushbullet.

 

I immediately freaked out and went to the dashboard, saw the red X and thought I was doomed. Without thinking, I didn't pause to collect diagnostics and shut down the server, in the hopes that my remaining data drive didn't die as well. It didn't, but now I have a broken system with no diagnostics or logs. Stupid me, what was I thinking?

 

I opened up the computer, cleaned out the dust and reseated the SATA and power plugs carefully, and not messing the order up. Then I reassembled the case and powered it back on.

 

image1.png shows what it's like right now. There's a X next to parity, the drive that has failed.

image2.png shows the dashboard. As you can see, the parity drive is 'faulty' and does not work.

image3.png shows the SMART status. Check out the parts I put in red. The raw value is completely messed up.

 

Looking at the SMART report, I'm 70% sure this drive is dead, but I'd like to resurrect it for now so I have a chance to buy another drive.

 

a) Should I remove this disk from Parity, pre-clear, and then add it back to the array?

(I don't think I trust parity data anymore, the data was surely fried. If preclear passes, then I might consider adding it back)

b) Or should I remove the drive, drill a hole in it and throw it away?

(Is it that dangerous?)

 

Attachment limit... I'm posting everything in my personal drive...

Run an extended SMART test on the parity disk.

Thanks @johnnie.black, sorry I'm a bit late but the test took over an hour. It passed.

 

Does this mean that it was a temporary head crash and all is well?

Use the same disk and re-sync parity:

 

-unassign parity disk (select no device)

-start array

-stop array

-reassign parity

-start array to begin a parity sync.

 

 

Thanks @johnnie.black, but just to make sure I'm going to do a preclear to make sure the drive isn't faulty.

 

Seems like it should be fine. Marking the thread as resolved.

I'm not so crazy about the runtime_bad_blocks and the reported_uncorrect.

 

I see no sign of cabling issues, which is good!

 

Keep a watchful eye for these values to increase. If they do I might consider a swap out.

 

Note that a "head crash" is a very bad thing. Means that the heads made physical contact with the spinning disk. It is not a temporary condition. Harmless use of the term, but sort of like saying "my car's engine temporarily threw a piston"

Haha yep, it's night here and I don't have any sense of what I'm doing which is very bad if I'm working around servers.

 

Hope I don't blow anything up... Currently there's no funds to buy another drive so if the parity drive fails then I'm... very very vulnerable to data loss.

Yeah, it's good that it passed the extenden SMART test, but both the SMART attributes and this:

 

I was working on my computer this morning when I heard a lot of sharp 'clicks' coming from the server.

 

make me think you may have more issues soon, if it happen replace it.

This.

 

Hard drive repeated clicking is typically one of two things. Bad power (PSU or cabling) or impending catastrophic HDD failure. BTW, bad power CAN cause the HDD total failure.
