Currently gives you 4.10.0-* kernel. OK, but I still cannot set caps without read access to "/" on cephfs volume, is there something else I must do ? # ceph auth get-or-create client.foo mon "allow r" osd "allow rw pool=cephfs_data" mds "allow rw path=/foo" Error EINVAL: key for client.foo exists but cap mds does not match # ceph fs authorize cephfs client.foo /foo rw Error EINVAL: key for client.foo exists but cap mds does not match Thanks, -- Yoann Moulin EPFL IC-IT _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
