"Unmountable: Unsupported or no file system" Cache problem after update 6.12 - Docker containers do not start anymore

[jotube]

hi community,

this is my first post here so bear with me if I do anything wrong

after updating to 6.12, I noticed that some of my Docker containers that were running on my cache (SSD) stopped working. After rebooting the server and starting the array, the cache now shows as "Unmountable: Unsupported or no file system". I have also backed up the flash but still get the message.

It should be noted that I had set the setting for "appdata" to "Prefer", so of course the affected containers are not started. Now I'm wondering what happened here and how I can recover my data.

If the only issue is the log tree this may help, don't stop the array and type:

btrfs rescue zero-log /dev/mapper/sdb1

Then re-start array and post new dags

Looks good so far, take the opportunity to update your backups if needed.

I am currently creating backups of the cache, using the mover. However, it has already been more than 10 hours for 30 GB. Before that, I set all folders in the share to "yes". As a test, I tried copying a folder from the cache to an unassigned device using "sudo MC". At the same time, I checked the logs and received the following message:

Does this mean that my hard drive is broken or just the format? thanks in advance.

Not related to your btrfs errors, but why do you have Docker enabled in Settings if you're not ready to run it yet?

This means some writes were lost, usually due to a bad firmware/controller, you will need to backup what you can and re-format the pool.

Ok thanks. I have already imported an old backup but will be a lesson to me. I will run backups more often. Thanks for the quick answers!
