[Linux-cluster] changing qdiskd config params

Hi Greg,

However, you need to make sure you cycle qdiskd within the timeout window, or you could have a node get fenced if it hasn't updated its slot on the qdisk in time.

thx for the informations. it would be fine if i can change the values 
without restarting cluster infrastructure with running services ...

mmh, i'm looking for a way to do this without an impact to the running 
system(s) :-) so the best way for this would be a command or something 
like this to see which parameters are currently used ..
