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.

Impressive fsck times

Member since:

Have a look at this benchmark:

With -O uninit_groups, fsck on ext4 runs 22 times faster than ext3 on that 5TB volume. Four minutes vs an hour and a half.

Presumably that will increase as volume usage increases, but still...
