NFS: submounts under exported mount

[daytooner]

I have an exported (via NFS) file system that contains other sub-mounted file systems (eg, DVD drives, ISO files, etc). While the sub-mounts show up locally, they aren't visible when the parent mount is exported.

In /etc/exportfs, the nohide option is specified for that export.

What else do I need to do?

TIA

I thought the "nohide" was only effective on mounts that existed before the export
takes place, but I could be mistaken.

What happens if you mount everything and then do an "exportfs -a" ?

DOH! I feel a bit stupid now. That never really occurred to me :-( .

The export that I want to use is pretty much in use 24x7 right now, so I can't really do anything with it till maintenance time. But I can at least create a test export.

Will let you know.

Thanks,

I still can't get NFS to export sub-mounts.

Here are the mounts:
On the server (from /etc/fstab):

/dev/VolGroup3W/LogVol3W /3W ext4 unhide,defaults 0 2

in /var/lib/nfs/etab:

/3W 192.168.1.0/24(rw,sync,wdelay,nohide,nocrossmnt,insecure,no_ro ot_squash,no_all_squash,no_subtree_check,secure_lo cks,acl,mountpoint,anonuid=65534,anongid=65534)

I then will do:

[root@Elmer 3W]# mount -o loop -t iso9660 /3W/iso/XXX.ISO /3W/iso/dvd/XXX
[root@Elmer 3W]# exportfs -a.

(XXX.ISO is an ISO image file)

On the client, from /etc/fstab:

elmer:/3W /mnt/3W nfs bg,noatime,nodiratime 0 0

and elmer is the server above, and in the hosts table as 192.168.1.103, and this client is 192.168.1.102.

The client doesn't see the sub-mounted ISO image /mnt/3W/iso/dvd/XXX, although it is seen on the server. Also, fwiw, it is seen with samba on my windows box.

Any ideas?

TIA
