[Linux-cluster] GFS mount problem

[Michael Krietemeyer]

Hello

We have setuped our small 4-node cluster with the RedHat 
2.4.21-15.0.3ELsmp Kernel and use the GFS 6.0.0-7 Package.

One cluster-node exports via gnbd two disks to the three other nodes. 
One of these exports is used as CCA-Device ond one for a GFS share.

Now we setup GFS like the example C.1. in the "Red Hat GFS 6.0 
Administrator's Guide" (three nodes, each as LOCK_GULM Server and GFS 
Client, fence method: manual). All steps work fine, except the mount.
On the fist node, the mount works. The mount on the second node blocks, 
until the node one unmounts the gfs share. (Summary: Only one node can 
mount the share at the same time).

Can somebody help?
