[Linux-cluster] Cannot mount GFS filesystem

[andremachado]

Hello,
presuming you already have a cluster.conf configured, all needed cluster kernel modules loaded and all cluster-suite running and started in correct order, did you gnbd exported the device to the other node?
GFS mounts local  devices only. Or what it sees as local (gnbd, iscsi, san, etc).
Also, your hostname seems to be localhost.localdomain, that is a sure source of problems, cited at documentation.
You need all hostmanes and ip addresses assigned for each node and configured for all others at each node, avoiding a dns, cited at docs.
I hope this helps.

Regards.
