You will need to patch your kernel (in your sdb test OS) and then

(for that you'll need to emerge sys-fs/reiser4progs). If you want
to be able to mount reiser4 from within your sda OS, you will need
of course to patch your current kernel to start with, alternatively
use a LiveCD like sysrescue which comes already patched. For
patches look in here:

The way I do what you are trying to do is start with the existing
OS on sda, partition sdb, tar contents of sda partitions into
corresponding sdb partitions and then modify fstab. Depending on
what you want to test you may not need grub installed into sdb's
MBR and you may not need a /boot in sdb. As long as you are not
going to remove sda from the machine you should be able to add a
couple of lines in the original grub.conf to select to
boot /dev/sdb, while using sda's MBR and /boot partition. HTH.
I could have swore reiserfs4 was in the kernel. Sure enough, it
ain't. I'll wait then. I don't want to take the chance that
something goes belly up then not have a bootable way to fix things.
reiser4 was never in the kernel and the odds of it ever making it there
were about zero (coding style issues and many other things that pissed
Linux off). And that was in the days when Hans was physically located
in a place where he was allowed to code.
For all practical purposes Reiser4 is dead. I haven't heard a peep out
of anyone claiming to maintain it for a few years now.
New question. I'm playing with LVM. What is the best file system to
use that with? I know LVM can shrink and grow so a file system should
be able to do the same, online would be great but not required. That
would be good for a / partition but not needed for the rest. I can
always go to single user and resize things.
I don't want XFS tho. I used it before and it was a total disaster. I
have a UPS but I also recall having to pull the plug when hal showed up
too. No need for a repeat.
Hmm, maybe I am thinking of ext4? Life's confusing. :/
