mount.ceph: unknown mount options: rbytes and norbytes
When trying to mount a cephfs with the
norbytes mount option, I'm getting the following output:
mount.ceph CEPH_HOSTS:6789:/ /mnt/test -v -o name=admin,secretfile=/etc/ceph/ceph.client.admin.key,norbytes
parsing options: name=admin,secretfile=/etc/ceph/ceph.client.admin.key,norbytes
ceph: Unknown mount option norbytes
(The output for the
rbytes option says the same except different option name)
The mount options (
rbytes) are documented in the man page of mount.ceph see https://github.com/ceph/ceph/blob/master/doc/man/8/mount.ceph.rst and http://docs.ceph.com/docs/jewel/man/8/mount.ceph/, but why is the
mount.ceph command saying they are unknown?
This feature is documented in hammer, infernalis and jewel version docs/man pages.
Is this a problem of my ceph/system configuration or is this feature that has not been implemented?
