I have installed Ubuntu 6.06 LTS and the updates reccomended onto a partition which had SUSE 9.0 with the reiser file system. And when I created partitions I tried to select the ext3 file system, but after the "Prepare the mount points" Ubuntu was successfully installed, but using the reiser file system. So can I change it to ext3 with the Disk Manager, or do I need to re-install Ubuntu to get it as ext3 file system?

Is it really important to have Ubuntu installed with the ext3 file system, and if so then what do I risk with the Reiser file system? And with a multi-boot system running Windows XP on a newer hard drive, and Ubuntu installed on the older hard drive, is it easy to change that file system with out format and re-install of Ubuntu Linux?

Hmm... Ubuntu will probably run on ReiserFS. However, RFS is a bit more complicated than ext3. Some normal Ubuntu operations may require different set ups in order to work on RFS. For instance, I know from experience that hdparm will not work on RFS without the kernel modules loaded at startup. You'll need to know how to make these changes if you plan on using RFS. I have 7 distros on my system and only use RFS for one (SuSE).

I could be wrong about this, but I don't believe you can "convert" file systems once a distribution is installed. I believe you'll have to reinstall Ubuntu and format the partitions as ext3 in order to fix that.

Wait for some more experienced advice before jumping the gun, though.

Yep, you gotta mkfs.....

On other notes, use XFS.

Anybody know when Reiser will get it's name changed?

It's not a brilliant idea to use XFS because although the performance is very good you have to have a separate boot partition using something like ext3 in order for grub to work with it otherwise you have to use LILO which is much more difficult to configure.

Yeah, I guess I never really need multiboot. I run Ubunto on my laptop, and VM's for anything else (no multiboot)

All of the larger Linux kernels that I configure are SAN attached, boot with EXT3 / create XFS filesystems on SAN.

Reiser blows.
