Okay, that works, I didn't realize I need a group for that. Maybe
that's something for the docs to clarify a bit.
Zitat von Anh Phan Tuan <anhphan.net@xxxxxxxxx>:
Not really sure what you want, but for simplicity, just move folder to
following structure:
/volumes/[Sub Volume Group Name]/[Sub Volume Name]
ceph will recognize it (no extend attr needed), if you use subvolumegroup
name difference than "_nogroup", you must provide it in all subvolume
command [--group_name <subvol_group_name>]
regards,
Anh Phan
