Hi,
I think you can specify the pool name in client settings.
for example, in our environment,
# rbd ls
rbd: error opening pool rbd: (2) No such file or directory
# rbd ls -p block
f7470c3f-e051-4f3d-86ff-52e8ba78ac4a
022e9944-122c-4ad0-b652-9e52ba32e2c0
Here -p pool_name was specified. that works.
