[Linux-cluster] CMAN & CLVM clvmd startup timed out

[Rainer Schubert]

Hi,

thank you for the fast answer. Now I have one question:

- It is possible to integrate the fencing-service on a working cluster?

I have working virtualisation enviroment with 50 VMs, so i can't take
them down.

best regards
