I’m running OpenSUSE 12.1, and I’ve noticed that all of my partitions are ext3. I’m assuming that’s because I’ve been running this forever, and during upgrades it’s kept the filesystems as is. In fact, the only reason it’s not running ReiserFS is probably due to the fact that the HD is only 3 years old and I did a full reinstall when I got it.
So, my question is: Should I convert my ext3 to ext4? Would I see any performance benefit? And if I should do this, what are the steps to do so? I’ve googled, but everything I’ve found is for older versions of opensuse.
First off, if all is well, I am not sure I would worry about a conversion until your upgrade to openSUSE 12.2. Second, you can’t convert a partition that is in use. So, download a openSUSE LiveCD, boot from it amd make sure it works OK. Third, backup any important data you can not afford to lose. Finally, if you are ready, here is a link I found on the subject:
