I installed FAI 3.2.12 and it seems like this bug may still exist in even 3.2.13. I've been able to reproduce it reliably in Vmware Server where the disk won't be formatted when it doesn't have a label. However once I put a label on it, it works fine. The other weird thing is the FAI banner shows 3.2.11 even though 3.2.12. Even after I upgraded to 3.2.13 the banner still shows 3.2.11
It does look however like I have the right modules, as the size and timestamps for the updated files look the same as one from a freshly installed 3.2.13 instace: /usr/share/fai/setup-storage# ls -al total 144 drwxr-xr-x 2 root root 115 2008-10-23 17:22 . drwxr-xr-x 4 root root 40 2008-10-21 14:03 .. -rwxr-xr-x 1 root root 35323 2008-10-22 06:48 Commands.pm -rwxr-xr-x 1 root root 11410 2008-10-22 06:48 Exec.pm -rwxr-xr-x 1 root root 10443 2008-10-22 06:48 Fstab.pm -rwxr-xr-x 1 root root 7037 2008-10-22 06:48 Init.pm -rwxr-xr-x 1 root root 25030 2008-10-22 06:48 Parser.pm -rwxr-xr-x 1 root root 24758 2008-10-22 06:48 Sizes.pm -rwxr-xr-x 1 root root 19793 2008-10-22 06:48 Volumes.pm
