That message is harmless -- it just means that the userspace mount.ceph utility doesn't do anything with the option, and is passing it through. You're seeing it because of the "-v" flag.

Running Luminous 12.2.7 on the client.It seems like mds_namespace is not a recognized option.The actual command is as follows:mount -t ceph -v -o name=admin,secretfile=/root/BlueCEPH.keyring,noatime,mds_namespace=depots_ec ceph-mon-r1z1n1,ceph-mon-r1z1n2,ceph-mon-r1z1n4:/ /mnt/pve/BlueCEPHfs/Scott Petersen - System Administrator

we're using a single cephfs in production since february, and switched
to three cephfs in september - without any problem so far (running 12.2.1).
workload is backend for smb, hpc number crunching, and running generic
linux containers on it.
