Today's problem - uncorrectable errors: 2

Featured Replies

Today I came home from work and tried to open my Sickrage UI and I'm getting a connection refused on http://192.168.1.44:8081/.

 

I did a scrub and got this:

 

scrub status for 1d177fe9-4d58-4f9d-8a29-e94ebcecc842

scrub started at Fri Jan 20 17:05:55 2017 and finished after 00:02:00

total bytes scrubbed: 15.15GiB with 2 errors

error details: csum=2

corrected errors: 0, uncorrectable errors: 2, unverified errors: 0

 

I've also attached diagnostics. I assume this is due to power issues. I did have the Fix Common Problems troubleshooting mode running. So I've got loads of .zip files at 30 minute increments, but I'm not sure which one would be of interest, so I don't quite want to spam those in there yet.

I've also run xfs_repair, but haven't found anything too damning.

Docker image is corrupt, delete and recreate.

I seem to have problems with Docker more often than...everything put together, really.

 

Any idea why that would be?

Have you read the Docker FAQ?

Yes, sadly I don't see anything as far as "Why do my dockers spontanously stop responding?" isn't on the list.

I think what trurl was getting at is their are 2 main causes of corruption on btrfs file systems

 

- unclean shutdowns (buy and install a UPS -> its a requirement for any server IMHO regardless of the OS)

- the file system / image filling up.  This is covered within the FAQ

Maybe not that specific question but just before that it was suggested that your docker img was corrupt and there is a lot in the FAQ that might help with that.
