Hi,
I'm not sure if that's what you need but ceph file layouts [1] could
meet your requirements. Your CephFS can consist of multiple pools
(replicated or EC), and with xattr you can define different pools to
be used for specific directories. Does that help?

Hello Samuel,
you can use the docs from
https://docs.ceph.com/en/latest/cephfs/file-layouts/ to find out how to put
a file on a different pool. Example: "setfattr -n ceph.dir.layout.pool -v
poolname foldername"
Ceph itself does unfortunately not provide tiering out of the box. You
therefore have
What you are proposing is called a hierarchical storage manager (HSM).
Cephfs does not have a built in HSM. Would be amazing if it did though.

could you elaborate what you mean with "re-layout"?

Dear Patrick,
Thanks a lot for pointing out the HSM ticket. We will see whether we have the
resource to do something with the ticket.
I am thinking of a temporary solution for HSM using cephfs client commands. The
following command
'setfattr -n ceph.dir.layout.pool -v NewPool Fold
