Changing my file system
 

Hi,

I'm using Fedora and would like to change the file system I use from ext3 to something like JFS.

Is it worth it? and how might I do that?

I'm thinking of copying all my files to usb, format, and put it back. That doesn't really make sense since the format program will be on usb and linux is running on a directory that is being formated.

doing a df yealds about 10GB of data on the partition Fedora is installed on.

Thank you.

What are you using the box for? Whether it's worth it will depend on that. There's a comparison of file systems on wikipedia that might be useful.

Generally I don't bother changing file systems until it's time to re-build the box. That forces me to evaluate why I wanted to do it and get some data that I can compare with after the change. Unless you're pushing the limits with your file system, you probably won't notice a change unless you measure it with a tool, rather than just how it "feels".

True, it may be more important to get the proper options in your /etc/fstab. Do you use noatime, nodiratime or relatime as mount options for your ext3 filesystem(s)?

Yep, a computer processor works with data in the RAM, hard disks are too slow no matter what. There are exceptions of course, like multitrack audio recording/mixing for instance where you have to pay attention to HDD performance.

EXT3 tips.
