Hi, all
I'm a newbie to Ceph, and just setup a whole new Ceph cluster (0.87) with
two servers. But when its status is always warning:
[root@serverA ~]# ceph osd tree

* serverA is 10.???.80, serverB is 10.????.78
* ntpdate is updated
* I tried to remove the pool and re-create it, and clean up all objects inside,
but no change at all
* firewall are both shutoff
Any clue is welcomed, thanks.
