Workaround for ReiserFS on root-filesystem

Workaround for ReiserFS on root-filesystem

[Thomas Bach]

Hi Folks!

I use ReiserFS for my root-filesystem while trying to upgrade to a newer 
kernel-version (still using 2.4.20) I got a error, that / could not be 
remounted read/write. After googling a bit I stumbled over the fact that 
ReiserFS as root-filesystem doesn't work since version 2.4.22 (or 
something like this).

So I asked myself if there exists any workaround/howto/something-else so 
   I could get away from making my root-fs to an ext3 one. Does anyone 
know something about it?

Thanks,
	Thomas Bach

Hmm.. It works perfectly fine for me with all 2.4.20-25 kernels, so you
should not trust everything you find on google ;-)
How big is your root partition? Which version of ReiserFS are you using?

I tried all kinds of versions (2.4.22, 2.4.25, 2.6.2 and as allready 
mentioned 2.6.5) non of them worked even after playing testing with all 
kinds of options...

The root partition is about 950Mb big (776 used...) and I am using
reiserfsprogs-3.6.11

 It works for me here:

/dev/ide/host0/bus0/target0/lun0/part4 on / type reiserfs (rw,sync)

Linux mother 2.6.5 #10 Sun Apr 4 08:59:08 CEST 2004 i686 unknown unknown GNU/Linux

It always worked - with 2.4.x, 2.5.x, 2.6.x up to 2.6.5.

OK! I am a bit confused. Could you perhaps pass me your /etc/fstab and 
grub.conf/lilo.conf entrys?

Thanks,
Thomas Bach (hopefull that he hasn't to reinstall all this stuff here)

 No problem. I'm using devfs, so I had to pass devfs names - the
standard ones as /dev/hda4 don't work.

My lilo conf:

image = /boot/kernel2_6
  root = /dev/discs/disc0/part4
  label = linux2_6fb
  append = "root=/dev/ide/host0/bus0/target0/lun0/part4"

and corresponding grub entry:

root (hd0,3)
title Linux_2.6
        kernel (hd0,0)/kernel2_6 acpi=force root=/dev/ide/host0/bus0/target0/lun0/part4 ro


And fstab:

/dev/ide/host0/bus0/target0/lun0/part4  /  reiserfs    defaults,sync   1       1
