RE: [Linux-cluster] GFS Node Limit?



Hi
Brilliant!

All sorted now...I had no idea about this bug. Is it documented anywhere
noticeable?
I had all my service servers named services-01, services-02. Renamed
them to serv-01 ... And it worked!
Thanks for all your help!

Gulm can only use 5 nodes in the servers list in
cluster.ccs/cluster/lock_gulmd/servers.  This could be why you are
having difficulties.  Try trimming the list and see if that yields
better results.

You may also want to make sure that your node names are uniquely
identifiable by their first 8 characters (this was a bug in version
6.0.0-1.2 of the RPMs, but since you didn't post the version of the code
you are using, I can only offer this as a suggestion ;)

There would be failure messages to the console stating that you didn't
have enough journals if that was the problem.  

good luck
