[Gluster-devel] ctdb project

[Brent A Nelson]

Since many people interested in GlusterFS also seem interested in 
fault-tolerance (and probably have clients that can't run GlusterFS), I 
though I'd point out an interesting project.  Take a look at:

http://ctdb.samba.org

It is designed to use a cluster filesystem (such as GlusterFS) shared 
amongst a cluster that can reexport the filesystem from multiple members 
of the cluster as if they were one (LVS-style).  Although obviously 
intended for Samba, it should work for NFS, too (they have instructions 
for it).

So, you could have a cluster exporting GlusterFS, parallel CIFS, and 
parallel NFS! A fault-tolerant, high-performance fileserving 
jack-of-all-trades; very cool (could make an incredible NAS product; add 
more bricks, serve them up in parallel, handle redundancy and failover)...

Of course, NFS reexport has to work first (SAMBA already seems to work 
fine on GlusterFS).
