1.there is few documents about cluster3,includehttp://sources.redhat.com/cluster/wiki/
do you know some where?
now i do not know what is redhat cluster?
2.gfs2 need /etc/cluster/cluster.conf,and express membership.
but clvm  seem do not have a cluster conf??
so what to make sure  nodes are clvm cluster number?
i guess  gfs2,clvm,need a cluster conf to conform membership?
3.if there can be  more than 1 cluster in cluster.conf? for example ,a cluster for gfs2, another for clvm cluster?
4 if i am boring ,forgive me if so.

thanks.

For gfs2 to be used it is good to use with the cluster but not necessarily check the release notes but if clvmd is used then cluster is necessary .

Cman is no more a kernel module but cman is the primary service which must be running to set up the cluster.

1.my storage base on fc-san.

i have to use a dfs with cluster-sense,i am testing gfs2.

in order to resize storage space, i want to use clvm + gfs2.

i want to know if it is required to install redhat cluser,cluster-storage ? and create a cluster?

2.my kernel 2.6.32, fc12, cman-3.0.17

i find no cman.ko,if it do not need cman.ko anymore?

thanks.

Hello,

Can you be a bit more specific with your request ?   Are asking how to you use clvm in RHCS ?    Whether you are using san, or any other method of external storage, you require to have the lvm2-cluster rpms in order to be able to use clvm with RHCS.
