Kevin, Thanks for the tip on CentOS. My working cluster is now: 3node 64bit AMD opteron 2GHz CentOS 5 (good) GFS 1 0.1.11(good) Apache 2.2.3 (good) Samba 3.0.23c-2 (good) NFS 1.0.9-16 (BAD) So I am avoiding Fedora and GFS2 until you've had more time to "bake" it. I am reading up on Wendy Chang's NFS linux-cluster postings to understand why NFS fail over is not consistent. - Has anyone successfully setup a failover NFS cluster? - Does nfsv4 work better? It appears by default fedora6 uses nfsv3 (tcp) client and is flaky.

Yeah, we have posted a large number of patches to fix most of the major problems with gfs2. Those should be percolating through upstream and then will get pulled into a fedora kernel at some point. How are the GFS1/FC7 rpms coming? Where should I look to download them? Not as well as we had hoped. We have been swamped with multiple RHEL releases/updates occurring pretty much at the same time. We will likely need to have our own version of the kernel since gfs1 requires access to three symbols in the gfs2 code in order to access the lock managers. If I can get a stable setup of GFS (1 or 2) working to show management I will be able to get a testbed for testing 64bit versions for you. So basically I need some flavor of FC and GFS that are stable so I can put it into production and show it off. Have you considered using the CENTOS instead of Fedora? Since CentOS essentially replicates the RHEL rpms, everything is already built and included?
