Changing docker cache to btrfs

[gevsan]

Hello.

 

Today I got a warning on my Docker_Cache ssd disk. 

I want to change this ssd disk and It's currently in xfs mode.

 

I bought 2 nvme disks that I want to use in btrfs insead for this Docker_Cache pool.

 

Do I just add the 2 nvme disks to the Docker_Cache pool and then change the file type to btrfs?

Will this format the drives? I do have backups of my appdata folder. 

Do i simply move the appdata folder into the pool after the change to btrfs?

 

Maybe there is a easy guide for this?

I just want this to be a painless operation

 

Best Regards/ Emil

Basically, yes.

 

You would make a backup of the existing appdata folder (either move it to the array with Mover or make a backup with the appdata backup plugin), and triple check that there's nothing else on the drive that you need saved

 

Change the number of slots for the Docker_Cache pool to be 2.  Change the filesystem to be BTRFS.  Start the array, format the drive and restore your backups onto the pool.
