Hi all;

I creat a new pool success,
# rados mkpool data1
and then I edit the code like this:
int fd = ceph_open_layout( cmount, c_path, O_RDONLY|O_CREAT, 0666. (1<<22), 1, (1<<22) , "data1")
and then the fd is -22!!!!!!!!!
when I use the data pool , it can success
int fd = ceph_open_layout( cmount, c_path, O_RDONLY|O_CREAT, 0666. (1<<22), 1, (1<<22) , "data")

You'll need to register the new pool with the MDS:
ceph mds add_data_pool <pool id>
