Hi:
Sometimes when i use ceph -s to query cluster status, it shows
all mons down (Hammer), but in fact monitor is not really down. from
the code it seems ceph -s not wait elect finish, so maybe quorum is
empty at that time?

What do you mean 'it is not really down"? Does the process run? If
yes, then had the process been bound to its port (netstat check) ? If
yes, then my next guess is a firewall issue that prevents monitors for
reaching each other. If no, then check the logs for the cause. One
possible case is that you run out of file descriptors.
