Another strange thing is that the last few (24) pg seems never get ready and
stuck at creating (after 6 hours of waiting):
[root@serverA ~]# ceph -s

488 active+clean
And I cannot retrieve the file at ServerA, which I put into Ceph cluster at
ServerB:
[root@serverA ~]# rados -p test32 get test.txt test.txt
2015-03-30 17:15:44.014158 7f06951b6700 0 -- 10.???.80:0/1002224 >>

2015-03-30 17:16:36.066125 7f0694fb4700 0 -- 10.???.80:0/1002224 >>

c=0x7f068000db10).fault
It looks it just hang there forever. Is it waiting for all pg to be ready? Or
the ceph cluster is at error state?

I think there no other way. :)

Thanks for the quick response, and it seems to work! But what I expect to have
is (replica number = 3) on two servers ( 1 host will store 2 copies, and the
other store the 3rd one -- do deal with disk failure, rather only server
failure). Is there a simple way to configure that, rather than building a
custom CRUSH map?

Hi Kai KH
ceph -s report "493 pgs undersized”, I guess you create the pool with default
parameter size=3, but you only have two host, so there it not enough host two
service the pool. you should add host or set size=2 when create pool or modify
crush rule.

Hi, all
I'm a newbie to Ceph, and just setup a whole new Ceph cluster (0.87) with

* 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.
