In kernel client based on RHEL8, there is no such "ceph.client_mountpoint" parameter. The subvolume path will be append after device, e.g. HOST0_NAME:_PORT_,HOST1_NAME:_PORT_,HOST_NAME:_PORT_:SUB_VOL_PATH. SUB_VOL_PATH is the result of "ceph fs subvolume getpath VOLUME SUBVOLUME SUBVOLUMEGROUP". My test case of kernel client is "mount -t ceph ceph:6789:/volumes/svgroup/userdata/cd8ad527-5a07-4d55-af25-9f224223473c /opt/userdata -o name=userdata,_netdev,noatime" Reported by: lshu_cn https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/4/html/file_system_guide/deployment-of-the-ceph-file-system#annotations:1a507770-295d-4eb4-a69f-0d32c3d2368a
