Cache Drive Error


njm5785

Recommended Posts

I had a drive on my unraid server fail last week. I ordered a new drive and put it in. Unraid rebuilt the new drive and all my files seemed fine. Then I tried to start my docker image back up and it doesn't seem to start. I also got notifications about a 187 error on my cache drive. I started digging around the menus and I found a screen that seems to highlight the issue (I attached a screenshot). I have no idea what it means and wondered if anyone could help out. Do I need to replace the drive? Is there something I can do to get my docker back up and running?

 

One more thing that might relate is that when I try and turn off the array I have to ssh in and force unmount the cache drive because it says it is busy. I know this is sorta random information but I am pretty new to problems with unraid. I set my server up almost 2 years ago and haven't had any issues until last week when one of my drives failed.

 

I am running unraid version 6.0-beta14b.

 

Thanks for any help someone can offer.

I thought maybe I should also attach a smart log from the drive. Here it is.

If you are on the latest v6 (this is a v6 support forum) it is very easy to give us a complete zipped syslog. Just go to Tools - System Log, and click the Download button.

 

Complete syslogs are always preferred unless you are able to diagnose them yourself.

Thanks for the info I had no idea how to get the complete syslog. I thought the log link to the right on all the pages was it.

Here is the complete one based on your instructions.

Disk 2 appears to need a new SATA cable:

Cache disk is having read errors:

The cache disk file system appears corrupted as a result:

Apr 20 12:43:03 Tower kernel: BTRFS: error (device loop0) in write_all_supers:3442: errno=-5 IO failure (errors while submitting device barriers.)

 

Run pre-clear on the cache disk and see if it passes.
