Okay, had a chance to dig around and sort this out.

Found a few pointers in the archives (some here http://tech.groups.yahoo.com/group/nslu2-linux/message/21936 some mirrored on nabble http://www.nabble.com/SlugOS-5.3,-Memstick---HDD----device-name-confusion-(sda---sdb)-td23927062.html ).

I listed the UUID of my HD' using the following...

Then wrote my /etc/fstab to reflect this...

The above links pointed me to root around in /etc/udev/rules.d and in /etc/udev/rules.d/local.rules I commented out the two following lines so that the block devices weren't automounted..

# Media automounting
#SUBSYSTEM=="block", ACTION=="add"    RUN+="/etc/udev/scripts/mount.sh"
#SUBSYSTEM=="block", ACTION=="remove" RUN+="/etc/udev/scripts/mount.sh"

...and that seems to have worked as the /dev/sda is all mounted fine on reboot (/dev/sdb had to be plugged into the desktop then back into the NSLU2, think I might take the hint of a new USB cable).

However, I can't seem to mount the file systems via NFS on my desktop.  I adjusted the paths in /etc/exports to reflect the mount points drives now have in /etc/fstab and also on the desktop adjusted /etc/fstab to reflect these too, but am told that there is an incorrect mount option specified...

On the NSLU2...

On the desktop (running Gentoo, hence mounting portage which will be synced nightly on the NSLU2)...

# grep portage /etc/fstab
slug:/mnt/portage       /usr/portage            nfs             auto,rw,users   0 0
# mount /usr/portage
mount.nfs: an incorrect mount option was specified

Ditto for all the other drives.  I realise this may be a problem on the desktop (client) side of things, but beyond changing the paths in /etc/fstab on the desktop nothings changed, and I've been pretty careful that I've not made typos and have the paths correct (checked three times now).

Can anyone see what I've done wrong or might have problems with.  I can provide more verbose output but I'm stumped at the moment.

Oh and one final question, how do I specify the swap partition when I'm using UUID, it only seems to be provided for formatted partitions and not partitions formatted for swap?  I guess I could put the device (/dev/sda2) in there, but that kind of defeats the object of using UUID's and may not be correct if for some strange reason things get assigned devices in a different order.


Thanks in advance,

Neil
