Re: [Linux-cluster] Unable to obtain lock



Hello,
again we had the same problem as stated in January. We installed the hotfix 
but it didn't help.
Again the whole cluster freezed, no node was allowed to rejoin the 
fencedomain.
Any ideas or do you need any more information?
Thanks and Regards Marc.
