The scheduler failure points out that you have a mismatch in
expectations (backend capabilities vs share type extra-specs) and
there was no host to schedule your share to. So a few things to check

- What is the share type you're using? Can you list the share type
extra-specs and confirm that the backend (your GlusterFS storage)
capabilities are appropriate with whatever you've set up as
extra-specs ($ manila pool-list --detail)?
- Is your backend operating correctly? You can list the manila
services ($ manila service-list) and see if the backend is both
'enabled' and 'up'. If it isn't, there's a good chance there was a
problem with the driver initialization, please enable debug logging,
and look at the log file for the manila-share service, you might see
why and be able to fix it.

Please be aware that we're on a look out for a maintainer for the
GlusterFS driver for the past few releases. We're open to bug fixes
and maintenance patches, but there is currently no active maintainer
for this driver.
