[Linux-cluster] IP Relocate Error / IP Restart error

[dan.deshayes at algitech.com]

Hi,
thx for the reply but I'm not sure thats my problem.
I couldn't find the syntax for disabling the exclusivity (I'm not using gui)
but as far as I've understood its disabled by default. I tried with
exclusive="0" (not sure if its the right syntax though) but didn't solve
my problem.
But if the cluster was running with exclusive-mode the relocation
shouldn't work either, right?
As stated earlier the service restarts fine aslong as the node already
have an external ip.
Anyone with other ideas. maybe related to the "IP monitor failing
periodically"? but I don't have any problems running the cluster aslong as
the bond0 interface goes down, so maybe not.

Regards, Dan.
