[Linux-cluster] Switching Master and Slave using lock_gulm

[Troy Dawson]

Hi,
I can't seem to find this answered anywhere, so if I've overlooked 
something, please point me in the right direction.

I have my GFS cluster running using lock_gulm.  I have 3 masters.  The 
one that I REALLY want to be the master came up last, so it is a slave. 
  Both the machine that is currently the master, and the machine I want 
to be the master should not be rebooted, or actually, loose their GFS 
file system ability (one is read/write, one is read only)

So the question is, is there a command in gulm_tools (or some other 
program) that will allow me to switch the master from one machine to the 
other without restarting any of the lock_gulm's.

Thanks
Troy
