Converting ext2 to ReiserFS or ext3

[bushwacker]

Ext2 has been standard for quite a while, but ext3 and ReiserFS are much more accurate and fast. How can I convert my hard drive to one of these filesystems (specifically Reiser) quickly and easily without loosing any data?
What about JFS?

Fisrst of all you'd need to get the patches for your kernel and compile support for desired fs.Once you have the support then make sure to backup or copy your partition/data to safe place,format/prepare for the new fs and mount the partition copy your data back on in and reboot to use new file system.

More information,detailes setup steps are included in docs with the patch(s) and on developers page.

IBM's JFS is very close behind with developement after reiserfs but with every new build it gets more polished and stable...i run it on a 5gig partition without problems and fsck thakes only few second to run,it's very fast...

Too bad SGI's XFS is lagging behind reiser and jfs...there are talks that either both reiser and jfs or one of them will be included in final 2.4.0 kernel when it's released...that's the future...btw there is a thread in general forum about reiser worth checking out.

Theoretically, I wouldn't have to do all this to upgrate from ext2 to ext3?21

Ext3 file system is just ext2+yournal addition so you are correct for ext3 fs support you'd not need to reformat your partitions only remount them to enable ext3...Hope this helps.

OK. Great. How exactly do I go about doing this...
