Many thanks! I now need to figure out how to pass arbitrary mount

Cheers!

K. I made it optional and used the package-provided defaults.
Your requested changes are implemented in ceph-cm-ansible. I've
attached the yaml fragments you'll need to pass on the
`teuthology-suite` command line to set up the partition, filesystem, and
cachefilesd service.
e.g., teuthology-suite ... ~/fs-cache-smithi.yml

I never actually tweak the defaults in my local testing, so let's start
with a default cachefilesd.conf as installed by the package. If we need
to tweak it later, then we'll go from there.

Ok, cool:
fstype: xfs or ext4 (either is fine)
size: ~50g or so would be ideal, but we can probably get away with less
if necessary
Getting there...

Can you give me an optimal cachefilesd.conf and I'll set that up in
ceph-cm-ansible too?
