Looks pretty good, thanks for writing this up. Minor notes: - While > 16TB is supported by ext4 disk formats, the mke2fs/e2fsck code to support this is not in any released e2fsprogs yet - I don't think the journal async commit blocks are enabled by default, so the "20% speedup" is not available yet. There is some work that needs to be done to make this feature 100% safe in case of corruption. - I'm not sure if enabling flex_bg on an existing ext3 filesystem is useful - you don't mention anything about the required e2fsprogs version. I _think_ (someone should confirm) that e2fsprogs-1.41.3 is the minimum version that anyone should use.
