  • Owner set to gdb

We seem to be proceeding apace with Greg adapting Quentin's stuff into a pacemaker cluster based solution. I've backported the pacemaker-related packages to F11 and Greg has checked in a first pass at an OCF resource for hacron.

gdb is no longer working on this.

I gather (one of?) the major concerns with this were how you ensure that you don't have two servers running cron jobs at once, without allowing the servers to shut each other down and thus spike our HTTP load (ie, the STONITH issue).

Sticking cron in a cgroup and using that to kill all descendants, without needing to actually reboot the machine, is one option for this that has come up:

  • -c scripts -i hacron, December 3rd, 2010
  • -c scripts -i hacron, October 28th, 2010
