My salt version:

[root@mon calamari]# salt-minion --version
salt-minion 2015.8.13 (Beryllium)

Please check whether files /var/cache/salt/minion/files/base/_modules/ceph.py existed on minion nodes.

@syf-zsxm

[root@mon calamari]# ll /var/cache/salt/minion/files/base/_modules/ceph.py
ls: cannot access /var/cache/salt/minion/files/base/_modules/ceph.py: No such file or directory

It doesn't exist, and what should i do to get it.

[syf-zsxm]

Does salt '*' test.ping work?
if work well, please try to run salt '*' saltutil.sync_all or restart the salt-minion.
if not, you have to re-establish the connection between salt-minion and salt-master.

PS: What's you calamari version? If 1.3, salt-2014.7 is a better choice.
