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.

* 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.
