Gluster users - Aug 2010 - NFS re-export a GlusterFS on RHEL 5.4?

Hi,

I'd like to re-export a glusterfs to a bunch of NFS clients.  The server
with the mounted glusterfs is running RHEL 5.4.  I'd like to use the nfsd in
the kernel if possible as the same server is already serving a few other (non
glusterfs) NFS shares.

On the server, the glusterfs is mounted like this:

---
root     13213  0.0  0.0 126924  2000 ?        Ssl  23:25   0:00
/usr/sbin/glusterfs --log-level=NORMAL --disable-direct-io-mode
--volfile=/etc/glusterfs/localhost-tcp.vol /export/jiv2_0001
---

and the export file looks like this:

---
/export/jiv2_0001/HY299
@biotechhosts(rw,no_subtree_check,no_root_squash,fsid=101)
---

When a NFS client tries to mount the export, it gets a "permission
denied" error.  /var/log/messages on the server says:

---
mountd[8221]:  refused mount request from <NFS client> for
/exports/jiv2_0001 (/): not exported
---

Any pointers are appreciated.  I am running gluster 3.0.5.

We have native nfs serving functionality, i.e. as a translator, that 
will be part of 3.1 release. In the mean time, you could use the same 
NFS server from a separate branch that is a lot more stable than the nfs 
in mainline. Note that this branch is only a beta branch for NFS and not 
for the remaining 3.1 targeted items like DVM. The usual caveats that go 
with beta release candidates apply.

Thats available at:

http://ftp.gluster.com/pub/gluster/glusterfs/qa-releases/nfs-beta/nfs-beta-rc10/

The documentation in there will show you how to export existing 
non-glusterfs directories also through Gluster NFS server.

Of course, you can always email here for questions.
