Linux While Ext4 was originally merged in 2.6.19, it was marked as a development filesystem. It has been a long time coming but as planned, Ext4dev has been renamed to Ext4 in 2.6.28 to indicate its level of maturity and paving the way for production level deployments. Ext4 filesystem developer Ted Tso also endorsed Btrfs as a multi-vendor, next generation filesystem and along with the interest from Andrew Morton, Btrfs is planned to be merged before 2.6.29 is released. It will follow a similar development process to Ext4 and be initially marked as development only.

You can't break the laws of physics though. If you are going to defragment then you have to have enough free space to move all your files around...

Anyone remember the DOS defrag util that moved around individual clusters? And it displayed a nice big map of the disk showing which sectors it was currenly moving. Free space requirements: one free cluster ;)

Yes, I remember it well, and this thread has got me stumped because of that. While a it is a *VERY SLOW* way to fragment a drive, it will do it as long as there is more than two(2) sectors free.

While newer fragmentation software is faster because they more entire file around, a followup using a sector by sector defrag would insure that the filesystem can reach 100%.

That kind of defragmentation doesn't fly today because the disks are just so large. It would take forever to go sector by sector with gigabytes worth of data, even after you've gone through a first-pass defragment.
