"Unmountable: Unsupported or no file system" on cache drive

Featured Replies

My docker instance just stopped and I couldn't restart it. I rebooted the server and now I can't mount my cache drives (raid 1), the only message i get is "Unmountable: Unsupported or no file system". 

 

I've tried to stop the array, umount the drives, start array, stop array, mounted drives and lastly started the array again, but it didn't solve the problem.

I cant remember if I'm using brtfs or xfs, but neither "xfs_repair" or "btrfs rescue zero-log" works.

 

Any ideas?

 

Running Unraid 6.12.3

What was the device you used? If not the below try again:

 

btrfs rescue zero-log /dev/mapper/sdc1

 

Then restart array

Thanks it worked flawlessly, I tried it against /dev/sdc1 and not /dev/mapper/sdc1

Hmm, I restarted the dockers service and the same error occurred again. What could the underlying problem be?

Pool is unmountable again or just a problem with docker? Either way post new diags.

Pool is unmountable. Now I tried to access my files from the cache without docker service started and it worked. As soon as I started the docker service some dockers started, but it was unable to start some dockers. And when restarting the array "Unmountable: Unsupported or no file system" occurred again

Run the command again, don't start docker, best to backup pool then re-format.

ok. thanks

Hi, i just encountered the same problem and the command did not fix it.

For me its an NVME that i use as a cache pool that has the appdata folder on it. I have backups of the content, but they are a few days old.

Any Ideas?

Okay, found another post and the following did the trick, but we will see, if its still a problem after a reboot.

 

xfs_repair -v -L /dev/nvme0n1p1
