Hey, Everyone,
I'm running SuSE Linux Enterprise Server 10 and trying to get a sort of
clustered file server setup going. SLES10 uses heartbeat for the clustering/HA
setup, and I've chosen GFS for the filesystem to back the system. I'd like to
use GFS because I want both file servers (and our backup server) to have access
to the file system simultaneously (the backup system can access it read-only).
If one of the servers fails I'd like to avoid the issue of having the backup
server remount it.
Anyway, I'd like to set up heartbeat with NFS and Samba shares for the
directories on the file system. I'm trying to use hb_gui to set this up, and I
have a few questions.
1) First, can I have both servers share out the same NFS volumes
simultaneously? I know Samba doesn't work well (at all) in this scenario
because Samba doesn't (currently) have a way of sharing file locking
information between multiple instances of Samba. I'm wondering if that's also
a limitation of NFS or if NFS can handle the file locking?
2) I need to know how to set up the resources, exports files, and Samba
configurations. Most of the configurations seem to point to having "normal"
filesystems (ext3, etc.), that are mounted when the heartbeat configuration
starts and move between systems as necessary. A lot of them also seem to have
the NFS service running on one system or another and not NFS servers on both
systems, which is what I'm going for.
Thanks,
Nick
