March 17, 20251 yr Recently, I upgraded my Unraid setup to version 7.0.0 (previously running 6.12.0). Before the upgrade, everything was working fine. However, right after upgrading, I noticed that Docker is not starting up. Checking the logs, I found errors like this: Mar 17 19:46:28 unraid kernel: BTRFS error (device loop3): read time tree block corruption detected on logical 137314304 mirror 1 I guess the fact that this happened right after the upgrade is just a coincidence. Could you provide some guidance on where to start troubleshooting this issue? unraid-syslog-20250317-1916.zip unraid-diagnostics-20250317-2112.zip Edited March 17, 20251 yr by ataman
March 17, 20251 yr Community Expert you may need to re import the btrfs volume... Release notes: https://docs.unraid.net/unraid-os/release-notes/7.0.0/#general-pool-issues v6 didn't check or write the config correctly and this may be the culprit... I would recommend stopping all dockers and go to main click on the disk and run a scrub and smart test. otherwise, this is early sings of disk failure or improper docker storage configuration.

You can just recreate the docker image: https://docs.unraid.net/unraid-os/manual/docker-management/#re-create-the-docker-image-file Then: https://docs.unraid.net/unraid-os/manual/docker-management/#re-installing-docker-applications Also see below if you have any custom docker networks: https://docs.unraid.net/unraid-os/manual/docker-management/#docker-custom-networks
