Looking for documentation; trying to build 5-node LCMC H/A LXC cluster #38

Hi,

I am very eager to use LCMC to accomplish the following:

5-physical-node H/A cluster
- makes LXC containers highly available (load balanced, if possible)
- uses Pacemaker and Corosync for fencing via Supermicro IPMI
- provide multiple ethernet bridges to each LXC
- failed LXC container restarts on same "hypervisor"
- failed hypervisor restarts all guest LXC containers on a peer hypervisor
- storage is software replicated, such that the cluster is self-contained (no external SAN)
- storage using DRBD + GFS2 or OCFS2? recommendations?
- proper locking for shared storage (if distributed locking FS isn't used, perhaps something like side-loading Ceph RBD plus good locking mechanism)
- Ubuntu 12.04 is preferred distro, but will also consider Fedora 19/20 and CentOS 6.x
- ability to force guest evacuation (e.g. in preparation for scheduled maintenance)

Please let me know if LCMC can help me in this task. Once achieved, I'd like to make a detailed write-up of the process.

Please let me know if I can clarify these goals in any way. My new hardware is gathering dust too quickly. :-)

Thanks, Joshua

you should be able to configure Pacemaker and DRBD with LCMC, if you have some problem let me know :)
