You can use namespace so you don't need separate pools.
Unfortunately the documentation is sparse on the subject, I use it with
subvolume like this
# Create a subvolume
ceph fs subvolume create <filesystem name> <subvolume name>
--pool_layout <pool name> --namespace-isolated
The subvolume is created with namespace fsvolume_<subvolume name>
You can also find the name with
ceph fs subvolume info <filesystem name> <subvolume name> | jq -r
.pool_namespace
# Create a user with access to the subvolume and the namespace
## First find the path to the subvolume
ceph fs subvolume getpath <filesystem name> <subvolume name>
## Create the user
ceph auth get-or-create client.<username> mon 'allow r' mds 'allow
rw path=<subvolume path>' osd 'allow rw pool=<pool name>
namespace=fsvolumens_<subvolume name>'
I have found this by looking at how Openstack does it and some trial and
error.
