Hi Ken,
Thanks for your reply.The ceph cluster runs well.
:~$ sudo ceph -s cluster 285441d6-c059-405d-9762-86bd91f279d0 health

I previously deleted some pools. So, the latest ID for the pool, 'rbd', is 6. I
guess the client probably tries accessing the first pool by default and then
got stuck. So, how can I change the pool ID into '0'?
Thanks,Strony

hello,
Does ceph cluster work right? run ceph -s and ceph -w for watching more details.

Hi,
I am a new learner in ceph. Now I install an All-in-one ceph on the host A.
Then I tried accessing the ceph from another host B with librados and librbd
installed.

But in Host A, I don't find any error info.zq@zq-ubuntu:~$ rbd list -lNAME
SIZE PARENT FMT PROT LOCK z1 1024M 2 z2 1024M 2
z3 1024M 2
The ceph.conf and ceph.client.admin.keyring in host B are the same to those in
host A. Any comments are appreciated.
Thanks,Strony
