export loopback mounted .iso`s failed
Subsystems (2)
Hello !
I have a cdrom-server based on SuSE 9.1 (kernel 2.6.4) wich exports all it cd-roms via nfs, too.
All CD-Roms (>50 so far) are loopback mounted on the server and exported to the public as a single nfs-share "server:/cdroms"
this works perfectly so far - but now i realize that this doesnt seem to work under suse 9.3 (kernel 2.6.11) anymore, because of (kernel based) nfsV4. I just dont see the contents of the loopback mounted iso`s - just empty shares.
how can i make this work with suse 9.3 and kernel based nfs ? I don`t want to "switch back".
regards
Roland

Hello !
I have a cdrom-server based on SuSE 9.1 (kernel 2.6.4) wich exports all it cd-roms via nfs, too.
Are these stored as ISO-files or are they really cdroms in some jukebox type device?

Why do you think NFSv4 would matter?
Anyhow, exports of loopback mounted iso-files works fine for me both with and without NFSv4 support:
lade:~# uname -a
Linux lade.trondhjem.org 2.6.12-rc3-up #1 Mon Apr 25 08:59:39 EDT 2005 i686 GNU/Linux
lade:~# mount -ro,loop=/dev/loop/0 /home/linux/Ubuntu/ubuntu-5.04-live-i386.iso /mnt
lade:~# exportfs -rv
exportfs: /etc/exports [6]: No 'sync' or 'async' option specified for export "localhost:/mnt".
Assuming default behaviour ('sync').
NOTE: this default has changed from previous versions
exporting lade.trondhjem.org:/mnt
reexporting lade.trondhjem.org:/mnt to kernel
lade:~# mount -t nfs -oro localhost:/mnt /tmp/gnurr
lade:~# ls /tmp/gnurr/
