Issues with Docker and VMs after moving data from Cache pool

[jvlarc]

Hello unRAID experts I'm in need of assistance with my unRAID server. About 1 week ago, I attempted to move my ZFS cache pool (2x 500GB SSD) to my BTRFS cache pool (1x 128GB, 1x 1TB). During this process, after all four SSDs were in the BTRFS cache pool, one of my M.2 SSDs (1TB) failed. Removing it from the cache pool rendered the entire pool unmountable, so I had to reinstall it and retransfer everything back into my array. Unfortunately, some data got stuck in the cache pool. I tried using unBALANCE to move the data, but it didn't work well. Then, I manually moved data out of the cache using MC and file manager. Since then, I've been experiencing major issues with my server and am now seeking expert help. I managed to reconfigure the BTRFS cache pool with the three SSDs (1x 128GB, 2x 500GB SSDs), but something seems corrupted. Some of my Docker containers still run, while others restart as if like new or are completely inaccessible. My Home Assistant VM doesn't work, although VNC shows it as started. I have the Backup/Restore Appdata plugin and tried using it to restore my data, but it didn't help. I would greatly appreciate any advice or assistance to resolve these issues. Thank you!

For the container, and assuming you have valid appdata, try recreating the docker image:

Also see below if you have any custom docker networks:

Thanks, @JorgeB I've tried that several times, but the issue still persists. I suppose the only thing I haven't tried yet is deleting the entire appdata folder and restoring from backup. Is that correct?

Also, regarding the VM issue: it shows as started through VNC, but the IP address doesn't work, and HA's local DNS also fails. I tried changing the default network source from virbr0 to br1, but no luck. Do you have any other suggestions?

[JorgeB]

You can try, but if it doesn't work it suggests the appdata is incomplete.

 

Cannot help with the VM, you can try re-posting just about the in the KVM subforum.

Thanks @JorgeB, It looks like wiping everything was the right move. My Docker containers are back up and running. Now, on to the VM...
