MCollective

I’ve just upgraded my MCollective Client to 1.3.1 and am finding that mc-find-hosts does not report 1.3.0 servers.

All machines are running Ubuntu Linux. The 1.3.1 client running Natty, the 1.3.0 client running Lucid along with both servers.

I run “mc-find-hosts” on a 1.3.1 client and the 1.3.0 server logs:

Yet I run “mc-inventory foobar” on a 1.3.1 client and the 1.3.0 server reports successfully:

Running “mc-find-hosts” on a 1.3.0 client experiences the same problem against a 1.3.1 server. Again, mc-inventory works.

All machines are running the discovery agent.
