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

pgmap v225126: 256 pgs, 1 pools, 345 bytes data, 10 objects

client io 0 B/s rd, 193 op/s rd, 0 op/s wr
$ ceph osd lspools
6 rbd,
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.From host B: I run python to access the ceph on host A.>>> import rados>>> cluster1 = rados.Rados(conffile='/etc/ceph/ceph.conf')>>> cluster1.connect()>>> print cluster1.get_fsid()285441d6-c059-405d-9762-86bd91f279d0>>>>>> import rbd>>> rbd_inst = rbd.RBD()>>> ioctx = cluster1.open_ioctx('rbd')>>> rbd_inst.list(ioctx).... stuck in here; it never exits until the python program is killed manually.But in Host A, I don't find any error info.zq@zq-ubuntu:~$ rbd list -lNAME SIZE PARENT FMT PROT LOCKz1 1024M 2z2 1024M 2z3 1024M 2The ceph.conf and ceph.client.admin.keyring in host B are the same to those in host A. Any comments are appreciated.Thanks,Strony
