Re: CephFS: convert directory into subvolume

Hi,
you'll need to have either both mount points mounted on your host or simply mount the root directory. I don't think there's a different method available to convert directories to subvolumes.

Zitat von jie.zhang7@xxxxxxxxx:

Eugon,

Thank you, however I'm am still lost. I can create a subvolume group, that I understand. The issue is '/volume/<group>' isn't a real directory on the host, it's a 'virtual directory' in cephfs. '/mnt/tank/database' is a real folder structure on the host. I can't `mv /mnt/tank/database /volume/<group>`

Re-reading the thread, is the answer basically:
1) Create group and subvolume
2) mount the subvolume onto the host and then move the data?

Or is there a more direct way to convert '/mnt/tank/database' to '/volume/<group>/database'

Thx!

Jie
