Hey everyone,
I haven't used fbsd in a little while and am preparing to go back to it for my web/mail server. Before doing so I was hoping someone might tell me if fbsd has anything interesting going on in the area of journaling file systems. Can it support xfs perhaps?

*BSD unixs dont really use/need journaling filesystems. I remember reading some good papers and explanations online awhile ago and will try to dig them up for you.

the BSD's use softupdates.

If you're installing FreeBSD 4.6 or newer, softupdates is enabled by default on your disks. They smoke. Untar a ports tree and look at her fly!

Thats great information. Thanks guys. You've proved this site is worth coming back to!

Hmm... that was supposed to be a smiley... maybe the recent xss trouble with phpbb has prevented that from working somehow.

Here you go instead :D

The Journaled File System for FreeBSD (JFS4BSD) Project has the goal of porting the JFS Technology from IBM/Linux to FreeBSD. It uses a log-based, byte-level file system that was developed for transaction-oriented, high performance systems. Scalable and robust, its advantage over non-journaled file systems is its quick restart capability: JFS can restore a file system to a consistent state, fsck times go down, and it is easy to fall-back to the last good state of the filesystem in a matter of seconds or minutes. The jfsutils is under a compilable state on FreeBSD.

Still what benefits does the journaling filesystem has over softupdates. Can anyone explain that to me?
