[Linux-cluster] timers tuning (contd)



Hi

Is there a similar rule with CS5 ? I mean if we
increase the heart-beat timeout, is there some
other parameters to adjust together ?

Thanks

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.
