I have tried mounting the cephFS as two different users.
I tried creating a user obuser with:
fs authorize objstore client.objuser / rw
And I tried mounting using the admin user.
The mount works as expected, but neither user is able to create files or
folders.
Unless I use sudo, then it works for both users.
The client.objuser keyring is:
client.objuser
key: AQCGodxfuuLxCBAAMjaSNM58JtkkUwO8UqGGYw==
caps: [mds] allow rw
caps: [mon] allow r
caps: [osd] allow rw tag cephfs data=objstore
Regards
Jens

Sorry, I was afk. Did you authorize a client against that new cephfs volume?
I'm not sure because I did it slightly different and it's an upgraded cluster.
But a permission denied sounds like no one is allowed to write into cephfs.
