We always welcome patches and code contribution to speed things up.

Default pcmk + corosync + cman for dlm support?

Fabio,

Thank you so much for your response. Currently I compiled cman (for
dlm and *_controld), pcmk,
corosync, OpenAIS from source, and my original pcmk cluster stack is
back up, and now with dlm
and almost o2cb support thanks to cman. A few questions:
* Any idea on David's progress of DLM from the unstable tree? Again,
we will be using this in a pcmk stack
* Just to make sure was the DLM package responsible for dlm_controld,
and ocfs2_controld.pcmk? If so,
are the plans to keep the ocfs_* support remain?

As for our current setup with pcmk 1.1.6, and Cluster3, we are getting
the following error from ocfs2_controld.pcmk:

I already answered this. Itīs next generation code. Itīs ready when itīs
ready.

ocfs2_controld comes from another project. You want to talk to the ocfs2
people about it.
