Hello All,

I am running into an issue and don't know why. Everything was working fine and all of a sudden now my docker service won't start. I have ran this command below "btrfs rescue zero-log /dev/sdg1" and seems to fix the issue and then it stops again. I have uploaded the logs. Any help is greatly appreciated it.

Thank you.

There are filesystem issues with the pool:

With btrfs, I recommend backing it up and reformatting.

Hey @JorgeB thank you for your prompt response. Do you happen to know the best way to back up that drive and reformat it to xfs and not btrfs? I keep having issues with btrfs and want to see if maybe xfs is better. I tried to follow this but I keep getting this.

root@Tower:~# btrfs restore -v /dev/sdg1 /mnt/disk1/restore/

ERROR: /dev/sdg1 is currently mounted, cannot continue

I have one cache pool already in xfs. Should I be okay if I copy all the files from btrfs to that XFS cache pool and then change the shares to the new XFS drive? or is it better to use directory?

Depends on how the files are organized on the source, you can create a folder named backup and copy everything there, then restore to the new pool.

Thanks seems I got it back to work. I appreciate your help @JorgeB
