Description Lon Hohberger 2006-10-10 13:37:43 EDT
Answers to frequently asked questions about qdisk need to be included in the
qdisk(5) man page.

* Include minimum qdisk size in documentation.
* Talk about the cman deadnode_timeout and the qdisk timeout and how they
interrelate, and how to extend the openais timeout on RHEL5 / FC6 / etc.
* Include some real-world examples with failure cases, recovery, expected
behaviors, etc.
Comment 1 Josef Bacik 2006-10-10 15:28:05 EDT
* Indicate that post_join_delay should be 2x the tko time for qdisk
* For two node clusters, cman still has to have the two_node="1" and
expected_votes="1" options set.

I think thats it for now.
Comment 2 Lon Hohberger 2006-10-11 13:04:03 EDT
* Documentation concerning cman<-->qdisk interaction is weak (or really,
Comment 3 Lon Hohberger 2006-10-11 13:10:19 EDT
* I don't think two_node is needed for 2-node clusters, which would obviate
post_join_delay.  However, I should note that it may be desirable to decrease
the CMAN join timeout in /etc/init.d/cman

devel NAK for 4.5 - removing from 4.5 list.  Any updates to the man pages would
be dependent on the current cman/qdisk relationship discussion that is ongoing
and would be made as part of that effort.  Lon, can we just close this one?
