[Lxc-users] [Pacemaker] ManageLXC Resource Agent

[Christoph Mitasch]

Hi Florian,

good pointer, I asked a while ago about a RA on lxc-users but didn't get
any response.

The existing lxc RA seems to work. I had to create the
/var/run/resource-agent directory (seems to be a known bug) and insert
the powerfail line (as mentioned in the description of the RA).

I will further test it and contribute back.

Regards,
Christoph
