Hello, a cluster from my friend has an strage issue with CephFS Permission. Ceph Version is 17.2.7 in cephadm. The Cluster was much older and was upgraded over years from 12 and moved to new hosts. When I create a cephfs user for my private cluster with "ceph fs authorize" I get permission like this. client.test2 key: <placeholder caps: [mds] allow r fsname=cephfs, allow rw fsname=cephfs path=/all caps: [mon] allow r fsname=cephfs caps: [osd] allow rw tag cephfs data=cephfs For my cluster this is working fine. But for the cluster from my friend I get only metadata access no file access. I figured it out that when I modifie the caps like this I get it working again. client.test2 key: <placeholder caps: [mds] allow r fsname=cephfs, allow rw fsname=cephfs path=/all caps: [mon] allow r fsname=cephfs caps: [osd] allow rw But this is a solution I do not wan't to keep and every auth createtd with "ceph fs authorize" is not working. ceph osd get-require-min-compat-client -> nautilus Any Ideas how to solve this?
