I've recently added support for automating the kernel branch test
matrix in the Ceph qa-suite [1]. This makes it so we're testing (a)
RHEL with its distribution kernel and (b) a random distribution with
the testing kernel. (A particular benefit of this is that you no
longer need to specify `-k testing` to teuthology-suite and therefore
don't accidentally use an obsolete kernel.)
What would be nice though is to specify the distro/kernel for the
kernel client role independently of the other roles. i.e. I could have
a RHEL kernel client and an Ubuntu 16.04 Ceph cluster. There are two
reasonable reasons for doing this: (a) break the distribution
specification of the cluster out of the mount matrix and (b) allow for
mixed distribution cluster testing.
I imagine it could look like:
roles:
-
daemons: ["osd.0", "mon.a", ...]
os:
type: ubuntu
version: 16.04
kernel: testing
-
daemons: ["client.0"]
os:
type: rhel
version: 7.5
kernel: distro
Thoughts? Anyone like to look into this?
