10.0pt;font-family:Arial;color:navy'>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.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>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).<o:p></o:p></span></font></p>

glusterfs has to be mounted with direct-io disabled for NFS re-export to work

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.</span></font><o:p></o:p></p>
