XFS with Thin Provisioning

[JavierC]

Hi, I have set up a thin pool for container creation. When I create Cts the filesystem is formated with ext4 automatically.

is it possible to create containers with XFS instead of EXT4 using thin provisioning?

Regards

Thin-provisioning is at the block storage level, so it does not matter what filesystem you run on top as long as it is able to discard free space. At the moment, I do not think that there is a way to change the filesystem, because it is hard coded in the source:

Thanks for your response LnxBil. I guess I will create common lvm volumes for use XFS with containers.

You cannot run XFS inside of a container due to the limitation I mentioned.

If I understand you correctly, you try to run
LVM -> xfs -> directory storage -> raw file -> ext 4 -> container
which will not solve any of your problems, just increase the complexity, number of layers and will at best yield the same performance as running containers directly on LVM like this
LVM -> ext4 -> container
