Hi,

 

I've been having issues out of the blue with Docker slowly failing to different degrees. Often a reboot is required to get it working again.

 

It will not restart containers giving an Execution Error 403. If I stop docker and try to restart it will fail to start. I did some searching and found I could start with a BTRFS Cache Scrub, so completed that, but it solved nothing.

 

I can see some BTRFS errors in my diagnostics, but not sure what the cause would be.

 

Any help appreciated.

First off all, update to 6.12.4 and apply changes according to the release notes https://docs.unraid.net/unraid-os/release-notes/6.12.4/#fix-for-macvlan-call-traces

or dont use macvlan


secondly, your pcie ssd is the culprit. The cause for it could be multiple things, but the outcome is the same, it drops offline.

Cache filesystem is going read only, making the docker image read only as well, this error:

 

BTRFS error (device sdb1): block=799209570304 write time tree block corruption detected

 

usually meant a RAM problem, but with current kernel apparently it can still happen without bad RAM, since you are using ECC RAM unlikely that the problem is there, suggest backing up and re-formatting the pool, or try zfs instead.

Thanks both, I have updated and followed the instructions in the release notes. Hopefully that solves it, but if it happens again, I think I'll backup and format the cache and start again.

 

What are the benefits of ZFS over BTRFS? I wont likely use the snapshots feature I hear so much about from general linux forums, so what benefits would I see?

They have similar features, and btrfs also supports snapshots, but zfs is considered more stable.
