Re: what partitioning rule am I not aware of?

In an excess of energy I decided to see how many different OSes I

encountered in FC6:


I figured 20 gig was about enough for each root, and decided to
create 7 small /boot partitions near the front of the disk (since
so many boot loaders have problems with big addresses) and 7 20
gig partitions after that for different kernels (my disk is a 160
gig sata drive).

Windows has no problems doing this, but fdisk -l won't print any
info about partitions after /dev/sda15 and if I try to install
FC5 on a system that actually has an sda16 and sda17 partition
(even if I don't try to use them for anything), anaconda blows up
at the partitioning stage when it is about to try to partition
and install.

If I go back to windows, delete the last two partitions, and
re-install, all goes smoothly.

Is there some rule I don't know about on the number of
partitions? Or is it a rule about the starting address of a
partition (can't be too big maybe)?

Its really very irritating that they keep making disks bigger and
bigger and software never seems to know what to do with them :-).

Try parted. Make sure you make the extended partition go to the end of the disk and then fill up the space in between. Also, fdisk in Debian will allow you to go beyond 15 (I have 26 total on /dev/hda). Not sure about /dev/sd* since I make large software raid partitions on my SATA drives and then overlay with LVs.
