I added this line:
10.10.10.10:6789:/ /mnt/ceph ceph name=admin,secretfile=/etc/ceph/secret.key,noatime 0 2
to /etc/fstab in all of my nodes and executed "mount -a" and works good but in next system reboot it doesn't mount automatically and I have to execute "mount -a" after each reboot (I add "/bin/mount -a" in all rc.local files in all of my node) but I want the better solution for my problem?
