Description

Copying the user comments here

Hey there, I found a potential cephfs issue I'd like to run by you before I
report an issue. cephfs subvolume create has the --namespace-isolated option,
which creates a namespace for this subvolume named fsvolumens_{subvolname}. This
has the issue that it does not include the subvolumegroup name, so if I were to
create two subvolumes of the same name in two different subvolumegroups, they'd be
in the same namespace subvolumegroups.

I am creating this tracker on behalf of the user so that it doesn't miss out.

Yes, this is a bug and needs to be fixed.
