Re: [Linux-cluster] Linux-cluster Digest, Vol 80, Issue 23



Hi,
 I am using RHEL5.4  and trying to make cluster using conga, i did
every  thing,  like in main server i installed luci* cluster* related
package using :"yum groupinstall luci* cluster*,
and same time installed cman*
and in other two nodes i have installed ricci* packege using yum.
now every thing is done, but in server when i am running "service cman
restart" its giving an error like " local  node name is not found in
main conficuration file and /usr/sbin/cman_tool: aisex daemon not
started ."   please have a look into my querry, as i am facing this
problem since many days.


THanks
Sandeep
