Hi, First of all, thanks for your previous tips on the Linux box, it was very much appreciated. I'm reading the different filesystems, when would you use XFS or JFS or ext4. If I'm correct currently Linux uses ext4, am i right? From the reading both XFS and JFS look like a great choice.
I wouldn't (and mostly don't) use ext4 for anything. The only reason that I would consider using ext4 is for large scale storage in preparation to migrate to Btrfs at which point I'd go with Btrfs and save myself the migration. ext4 is NOT backwards compatible. ext4 file systems with extents cannot be mounted as ext3.
For large scale storage I prefer ZFS. It does almost everything, and it does everything well. Btrfs is my other choice for when ZFS isn't a good choice.
System volumes get ext3. None of ext4's features are of any benefit to system volumes and can sometimes be detrimental due to the lack of backwards compatibility.
Red Hat is backing XFS for RHEL 7. That's good for XFS and might make it viable as a replacement for ext3 on system volumes. XFS may be good for certain types of large scale storage where performance is a higher priority than absolute data integrity.
