resize_reiserfs, free space in front....

[julius Junghans]

Hi,

i would like to grow my reserfs partition, the unsued space is in front 
of my root partition, between swap and root partition.
as stated in the resize_reiserfs manpage:

.......This can be done using cfdisk(8) for partitions, by deleting the 
partition and recreating it with
       a larger size (assuming there is free space after the partition 
in question).  Make sure you re-create it with the same starting disk
       cylinder as before!  Otherwise, the resize operation will 
certainly not work, and you may lose your entire filesystem.....

the same starting cylinder wouldnt change anything in my case...
is it possible what i want todo with resize_reiserfs?
- if yes then the manpage should be updated.

greets
julius

Reiserfs partitions, when resized; the beginning MUST stay fixed. 
This limitation also applies to ext2/3 filesystems.  The only
filesystem I know of in which the front of the filesystem can be moved
is FAT; which can't be practically used for linux, IIRC.

The solution is to make partitions as early on the disk as you'll ever
need and put everything else at the tail end (e.g. FAT at the tail
end).  IIRC, LVM should also be able to manage around this; although I
don't remember perfectly.
