Have a problem with NFS mounted disks.
On a Debian server (NSLU2) I added two disks to use as backups ('BackUp_1' & 'BackUp_2') and a recording disk ('Inspelningar') for a HTPC.
Disk 1 has 2 partitions 'BackUp_1' and 'Inspelningar'.
Disk 2 has 1 partition 'BackUp_2'.

Here are outputs of 'fstab' and 'exports' and 'mount'
-----------------------------------------------------
raivo@NSLU2:~$ cat /etc/fstab

When I try to pick up the NFS volumes on my desktop (zkab - 192.168.0.4) I only see the subdir

/home/raivo/BackUp_1
/home/raivo/BackUp_2
/home/raivo/Inspelningar

but not the files in the subdirs.
I have used autofs at my desktop with following:

raivo@zkab / $ cat /etc/auto.master
#
# Sample auto.master file
# This is an automounter map and it has the following format
# key [ -mount-options-separated-by-comma ] location
# For details of the format look at autofs(5).
#
/nfs /etc/auto.nfs --ghost

----------------------------------------------------
raivo@zkab / $ cat /etc/auto.nfs
Arkiv_X -fstype=nfs,rw,hard,intr,rsize=65536,wsize=65536 arkiv-x:/home
Arkiv_Disk -fstype=nfs,rw,hard,intr,rsize=65536,wsize=65536 arkiv-x:/Arkiv_Disk/home
NSLU2 -fstype=nfs,rw,hard,intr,rsize=65536,wsize=65536 NSLU2:/home/raivo/
NSLU2_Disk_2 -fstype=nfs,rw,hard,intr,rsize=65536,wsize=65536 NSLU2:/disk_2

----------------------------------------------------
Also I don't understand why /home/raivo/Inspelningar/DBMovie/DB1->DB3 don't get mounted in server NSLU2 since 'showmount'
gives me strange output ... where does '/home/raivo/DBMovie/DB2' and '/home/raivo/DBMovie/DB3' come from ... outer space maybe:

raivo@zkab / $ sudo showmount -a NSLU2
All mount points on NSLU2:
192.168.0.10:/home/raivo/DBMovie/DB3
192.168.0.2:/disk_2
192.168.0.2:/home/raivo
192.168.0.4:/disk_2
192.168.0.4:/home/raivo
192.168.0.9:/home/raivo/DBMovie/DB2

I have spent hours to trying to get it work ... but can't figure out where I have missed.
(BTW ... the server 'arkiv-x' works OK and I get the NFS volumes correctly on my desktop)
