Btrfs to xfs docker image

[ucliker]

How do I go about changing my docker image from Btrfs to xfs in unRAID 6.9 rc2?

[Squid]

Settings - Docker.  Stop the service

 

Hit the checkbox and delete the existing image

 

Change Docker - data root from BTRFS vdisk to XFS vdisk

 

Re-enable the service

 

Apps - Previous Apps, check off what you want installed and hit install

What are the main changes when switching Docker data-root?

 

In help there's no explanation.

From BTRFS <--> XFS, really no difference

 

From image to a folder, then multiple advantages.  No pre-defined space, the "image" grows and shrinks according to usage.  In theory, the least amount of writes to the drive, and would also be the fastest access method, although in practice you would never see the difference.

I have removed my cache drive (disk was broken) and moved the docker image to the main pool - hence from brass to xfs.

The image is still xfs. Does that matter?

(I have also some instability... and wonder if this could be a root cause).

Beside that: any advise how to convert?

I don't want to re-buil all my docker (there are still several settings manually made and not backuped for separate restore)

Doesn't matter.

You have to.  No way around it.

Doubtful
