[Linux-cluster] CS5 still problem "Node x is undead" (contd.)

[Alain Moulle]

Hi

As told before, the patch :
http://sources.redhat.com/git/?p=cluster.git;a=commit;h=b2686ffe984c517110b949d604c54a71800b67c9
does not solve the problem for my configuration ...

Just an idea/question : could this problem be also linked
to the defaut value of token ? Or has it nothing to do with it ?
Because currently, I have this problem with a Quorum disk
configured and no token record in cluster.conf, so token
is at its default value ...

???
Thanks
Regards
Alain Moullé
