Drive kicked out of array, is it dead?

Featured Replies

Hello,

 

This morning I woke up to my unRAID machine having kicked out my Drive2 out of the array. When I hover over the drive in 'Main' it says "Device is disabled. Contents emulated". I did some searches and it seems like the disk is a goner but I was hoping someone could help me confirm that - I'm a beginner when it comes to unRAID. 

 

For a brief history, I had about 200 errors on this drive in the past, then about 2000 yesterday. I ran several short SMART tests which all passed. My machine completed parity early this morning without issues. I tried running a long SMART test but I think it was interrupted by an automatic parity check. I tried switching both the SATA cable the drive is using and the port on the motherboard it's connected to, neither one helped the situation. It does appear that the drive is quite loud when spinning up and down, honestly it's been like that for a while and I thought it was just normal with my machine and the case I was using but now it appears to be solely from that drive. I downloaded the "Scrutiny" app and all of my disks pass.

 

Thanks in advance!

SMART for disabled disk2 looks OK. Emulated contents are mounted and have about 1.4T of data so should be OK.

None of that will enable a disabled disk. It has to be rebuilt because it is out-of-sync.

Since you rebooted after the drive became disabled, can't see the cause.

Thanks for your help. That managed to get the disk back into the array and it was working well.

 

Now after another parity check the drive was kicked out again, but once again SMART is showing no issues so I'm not sure what's going on. Am I dealing with a potentially bad drive? I have a replacement ready if needed. I attached a new diagnostics file and haven't restarted the system so hopefully it has some more information than last time.

SMART for disk2 looks OK and emulated disk2 is mounted with about 1.5T contents.

 

But, not entirely clear that connections are to blame.

 

See if you can complete an extended self-test on disk2.

I'm running the extended self-test on disk2 but I believe it's stuck at 90%. I started the test yesterday evening and let it run overnight and it's still 90%...

  • Author

Hi, just a quick update. The extended self SMART test completed without error. It looks like it was stuck at 90% for some time but now it's completed.

Well, I guess that makes the connections the main suspect then.

 

Check connections, SATA and power, both ends, including power splitters (probably don't need any splitters since not many disks).

 

Plugs should sit squarely and firmly on the connector, all cables should have some slack, and don't bundle data cables to make things "neat".

So should be OK to rebuild.

  • Community Expert

During rebuild, should be lots of writes to rebuilding disk, lots of reads from all other disks, zeros in the Errors column for all disks.

Thanks a lot for your help. I've started the rebuild and i'm crossing my fingers for zero errors for the disk. I'll report back when the rebuild is complete.

The rebuild completed without errors so I suppose I'm good to continue using the array. I'm wondering, however, if the disk keeps getting kicked out should I just come back with new diagnostics or make a new thread? I'm a bit concerned with the disk getting kicked out a few times now.

Diagnostics with the array started is preferred. Did you do the rebuild in Maintenance mode? No way to tell if anything is mountable without the array started in normal mode.

Yes I did the rebuild in maintenance mode and then stopped and started the array. Everything looks to be working well now. I'm just wondering about in the future if/when the drive gets kicked out again.

Looks good.

 

Just a tip.

 

Your array won't be able to spin down with your dockers running on it.

Got it, thanks. I'm new to docker, I just have the one app running on it for some more info on my drives.

 

Unfortunately, it looks like my feeling was right. The drive got kicked out of the array again when I was running a backup of one of my PCs to the NAS... :( diagnostics attached

It's logged as a disk problem, run an extended SMART test on that disk.

Well, I'm running the test and the disk doesn't sound good. I'm pretty sure I'm hearing clicking and grinding from the disk. I'll wait to see what the smart test results in and post updated diagnostics when it's done

If the tested passed, the disk should be OK, but not every issue is caught by that, I would swap cables/slot with a different disk and try again, if the issue follows the disk, replace it.

Thanks. I did replace the cable originally and swapped the ports on the motherboard and its still happening so I guess it's time to replace the disk. Just a shame since I didn't really use it that much. Good thing I bought a replacement already. Any tips for checking the new drive to make sure it won't fail early?
