[Linux-cluster] GFS on CentOS - cman unable to start

[Patricio Bruna]

Hi,
The error log is clear

---------
Jan  5 13:40:24 testbench06 openais[3939]: [MAIN ] local node name  "test01.gdao.ucsc.edu" not found in cluster.conf
---------

And is related to the email i sent before. Give a try, you don't lose anything.
