Mounting Ceph File Systems Permanently in /etc/fstab
The fstab entry for cephfs on the tutorial is:
mon1:6789:/, mon2:6789:/, mon3:6789:/ /mnt/cephfs ceph name=admin, secretfile=/etc/ceph/secret.key,_netdev, noatime 0 0
While, it may be
mon1:6789, mon2:6789, mon3:6789:/ /mnt/cephfs ceph name=admin, secretfile=/etc/ceph/secret.key,_netdev, noatime 0 0
Otherwise it will complain an mount error:
mount error 2 = No such file or directory
