It would be ideal if the clients in such testing had a dedicated
filesystem mounted on /var/cache/fscache, so that if it fills up it
doesn't take down the rootfs with it. We'll also need to have
cachefilesd installed and running in the client hosts.
Is it possible to do this in teuthology? How would I approach this?
I think I can make this happen pretty easily in ceph-cm-ansible. What
I'd need from you is desired filesystem type and size. Once I'm done
with my end, we'll need to create a cephlab.ansible overrides yaml
fragment to stick in that suite's qa directory.
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
Can you give me an optimal cachefilesd.conf and I'll set that up in
ceph-cm-ansible too?
