Well, I ended up finding that I had to mount with 'glusterfs' rather than using a mount command to get this to work properly. Perhaps it was an error on my part there, but I got it working in general. The issue now is that when disabling direct-io it brings gluster from at-disk speeds to a crawling 18-24M/s. This means when I want to export through NFS it further slows things down, somewhere in the range of 4-7M/s. Given that this is over gigabit Ethernet I should expect ~100M/s in good conditions and when simply reading/writing plain files over NFS this is the case. I did try unfs3 and turned back on direct-io and there are speed increases, but even when using plain filesystem, unfs seems to only be able to run about 24M/s tops. I'm not sure if this is an issue with the fuse lib/module, but certainly if I want to do any real work over NFS this isn't going to be a workable solution (either way, unfs or plain nfs with disable-direct-io). Any further suggestions to get this working (different fuse library, etc.) or at this point is this just how things will be with gluster+nfs?

You can disable direct-io using --disable-direct-io option to glusterfs. regards, On Mon, Apr 13, 2009 at 11:06 PM, Justice London <jlondon at lawinfo.com> wrote: Has anyone successfully gotten NFS exports of a gluster filesystem to work properly? When the export is mounted, file-names and folders can be properly created, but actually writing data to any of these files or folders results in a permissions/write error. I can send out further details on configs, etc. but perhaps someone has simply encountered this before and worked around it.
