[Linux-cluster] qdisk heuristic and chicken/egg dilemma

[Reiner Rottmann]

Hi!

Say you want to configure a cluster node by using a quorum disk so that it 
survives when the particular node runs a certain cluster service.

Such a scenario is even stated in the man page QDisk(8):
---%------------------------------------------------------------------------------------------------------------
For example, a user may have a service running on one node, and that node must 
always be the master in the event of a network partition.
---%------------------------------------------------------------------------------------------------------------

Then in my opinion you have a chicken/egg dilemma because you might need the 
additional vote of the quorum disk to get a quorate cluster (which again may 
run the rgmanager that is needed for the heuristic).

How would one solve this dilemma in a straightforward way?

Best regards,
Reiner
