Re: 16TB ext3 mainstream - when?

2TB (2^41 bytes), with 4kB blocks (most common) it is 8TB (2^43 bytes)

Ah, although a max of 4kB is documented in my e2fsprogs-1.39 manpage, I can override it (e.g. -b 65536, but I cannot mount it then). OK.

The major problem at this point is e2fsck time, which is about 1h/TB for
fast disks, at minimum (i.e. no major corruption found).  One of the
goals for future ext4 development is to include checksums into the fs
to allow online sanity checking, and also speed up e2fsck in various ways.

I'm tracking -mm, hopefully ext4 will be included in it anytime soon...

Thanks,
Christian.
