While doing an investigation on SELinux and what filesystems to use I came across XFS, now I don't know much about linux filesystems, so, IYHO whats best: ext3, xfs or what?
Thanx for any replies.

Unless you are doing very specila stuff like huge files or huge numbers of files, you really do not need XFS and can stick with ext3 which is the Fedora default.

See: http://oss.sgi.com/projects/xfs/

If you want more particulars.

The "best file-system" is the one that works for you reliably and satisfactory and which is supported by your Linux distribution. Fedora Core can install on XFS and ReiserFS with a hidden installer option and also includes the tools to use them, but those filesystems are not supported like ext3.

ts one thing that bugs me about Fedora/Redhat. Reiserfs has been used by other distros "not as a hidden option" but Redhat still doesn't show it as one of the available options.

There's a difference between offering filesystems and feeling about good such an option. I assume that the Red Hat developers have good reasons and specific requirements why they prefer ext3, e.g. ReiserFS and JFS don't support extended [security] attributes as needed for SELinux, or lock up with unstable or unfinished patches. Somebody must really track the changes in upstream kernel, SELinux and other technologies, and the specific requirements with regard to features like LVM2, to understand a decision. I could go on and mention users of the other distributions, who avoid ReiserFS like the plague, after they have been burnt severely by reiserfsck a couple of times.

ext2 is the best FS by far

I wouldn't use ext2 if you have a large harddrive, it takes _forever_ to check the filesystem.

IMO you should use a journaling fs, ext3 or reiserfs (which has never given me any trouble...) are the most popular I believe.
