5. An NFS server

Although I like to try a different stuff (see further), I need a reliable nfs server for archiving purposes. Debian has proved to be a reliable installation, so I decided to go back to debian for my NFS. First install the nfs server:
apt-get install nfs-kernel-server nfs-common portmap

All my disks are on a USB-hub. For a reliable boot, I have to unplug the hub and plug it in when the system is up. That means that the disks cannot be in /etc/fstab. I decided to make a little script that automatically mounts all that is connected and exports them as well (edit for your own use if you want it). For those interested:
aesopos:/# df                                                                                  
Filesystem           1K-blocks      Used Available Use% Mounted on                                          
/dev/sda1              2064144    351024   1608216  18% /

/dev/sdf1            961432072    204568 912389504   1% /media/WD_ELEMENTES_E 

That's 4.5 Terra. For mounting the stuff on clients, I use this script.

Why would anyone put so much diskspace on a relative slow access, you might ask. Well, as backup. I backup my important data every day with cp -rup --backup=numbered to those nfs-mounted disks. It is faster and less cumbersome than using tapes.

One drawback is that the nslu2 has not enough memmory to do an fsck on this kind of disks. So, when you reboot, you'll need to do the fsck on another computer before plugging them in. Of course, if you had a recent reboot and a clean shutdown, you do not need a complete fsck.
