8 Specifying "users" in that context doesn't make sense. Try creating an
9 entry in /etc/fstab. For example:
10
11 192.168.44.68:6789:/ /mnt/ceph ceph users 0 0
12
13 Then see if you can mount by its mountpoint:
14
15 $ mount /mnt/ceph

22 It's not a driver option. /bin/mount is suid root and refers to fstab to
23 decide whether a non-root user should be allowed to mount.
24
25 Generally speaking, regular user accounts should not be added to the
26 disk group. That provides raw read/write access to block device nodes
27 such as dev/sda, which is a potential risk both in terms of safety and
28 security.
