[Linux-cluster] CS4 U4 / timers tuning

Thanks Chrissie

And is there a way to change the dlm lock_timeout with
a parameter in cluster.conf ?

The DLM's lock_timeout should always be greater than cman's
deadnode_timeout. A sensible minimum is about 1.5 times the cman value,
but it can go as high as you like.

This isn't exactly 'documentation' but it does briefly describe the cman
