Time to attach some storage to your home network! I used to have a web / samba server for over five years running Slackware at first but Ubuntu since version 4.04. Given the noise and energy consumption I got rid of the large server system and decided to go for a more energy-efficient solution: a NAS. Read the rest of this entry »
I experienced some problems writing to my ubuntu backup server. The machine runs rsync every night to grab backup2l backups from production machines. The problem seems to be a vfat system (why I still use such a crappy format you wonder… it is simple enough to also work under MS windows). Anyway… found some good posts on this:

Now, the problem is exactly as explained in this post, yet the keypad stuff has nothing to do with it. Checking /var/log/messages yields nothing. Dmesg, however, goes berzerk:
[88396.976584] FAT: Filesystem error (dev sda5)
[88396.976585] fat_get_cluster: invalid cluster chain (i_pos 535540750)
Ok so I guess we’re having a faulty vfat system on our hands.
Luckily, somebody had the same problem with a vfat on a memory card:
So the problem can fixed:
sudo fsck.vfat /dev/sda5 -w -r
What this does: fix the FATs (which were for some reason munched up). -w means its immediately written to disk and not to memory to be written all the way at the end (although the command did not take long). -r means it asks the user what to do. This fixed the problem with an “Unable to create unique name” message from dosfsck when using -a (automatically repair).
Say you have a workstation on which you have some valuable data (say, a Master’s Thesis 🙂 and you would like to have it automatically backup to a remote server. There are some excellent howtos out there on the web so I won’t go into too much detail, I will just report on how I did it.
