- NTFS? As in the filesystem for Windows NT? That uses a Journal for
- preserving the synchronous nature of its operations. Of course the
- journaled ext2 will be slower than the current one---about half way
- between the speed of FFS and the existing ext2, but with much greater
- reliability and fsck times than either. Hmm I wonder if you could do
- what McKusick does, and splat out the directed partial ordering to disc
- just before doing most of the ops, thus gaining most of the speed of
- ext2 and the reliabiltity of
- a journaled FS? Food for thought :-)
-
- Is there a URL for the journaled ext2FS project? I'd quite like to do
- some porting over of this as/when it's nearing completion.
