FreeBSD Today Jeff Roberson committed his patches to FreeBSD 9 for adding journaling to UFS. No more background fsck after unclean shutdowns! This is a major landmark in the history of UFS, with 11000 new lines of code (and about 2000 removed). Much of the work was done in collaboration with Kirk McKusick, the original author of FFS and Softupdates, under sponsorship form Yahoo!, Juniper and iXsystems. Jeff's blog contains quite a lot of technical information of his work. There's also information on the FreeBSD mailing lists.

I don't think that *BSD FS needs to be replaced by anything. It's one of the most rock-solid [and proven by many years] FS I've ever used and I used/am using quite a lot of FSs [not a single data loss on UFS/FFS. ext2/3, NTFS made it couple of times].


It is solid. But the one you admire, OpenBSD, doesn't even support journaling....

You know, when it comes to OpenBSD, it doesn't matter how many unproven 'features' OS has. It's all about stability and security here ;)
And yes - I am using OpenBSD among other OSs and it performs very well on its default FS.
Needless to say I don't need journaling at all, mostly because of its nature - it simply makes my data more vulnerable to loss and - as some of other posters have said - it doesn't really make that much difference [ca. 1 min? not much, honestly].

"I have done some fsck benchmarking. I recovered an 80% full 250gb volume that was doing a buildworld with 8 parallel processes in .9 seconds. The traditional fsck took 24 minutes."

explain how journaling makes data more vulnrable to loss.
