We're trying to create a 27TB partition on openSUSE 11.2 x86_64 and seem
to be running into issues with e2fsprogs. Here's what happens:

root/bebd1$ mkfs.ext4 -v /dev/sdd1
mke2fs 1.41.9 (22-Aug-2009)
mkfs.ext4: Size of device /dev/sdd1 too big to be expressed in 32 bits
using a blocksize of 4096.

root/bebd1$ uname -a
Linux bebd1 2.6.31.5-0.1-desktop #1 SMP PREEMPT 2009-10-26 15:49:03
+0100 x86_64 x86_64 x86_64 GNU/Linux

All hitherto posts related to this problem seem to indicate that the
underlying tools, such as mkfs itself, are still 32-bit even on a 64-bit
system and that fixing this is top priority. That was as of April 2009 -
is it possible that this issue has not been resolved yet?

Or, to be more specific: what do I need to do in order to create a 27TB
ext4 filesystem?

Thanks,
Martin




Martin,

This is what I get from my system on the binaries:

/sbin/mke2fs: ELF 64-bit LSB executable, x86-64, version 1 (SYSV),
dynamically linked (uses shared libs), for GNU/Linux 2.6.4, stripped

/sbin/mkfs.ext4: ELF 64-bit LSB executable, x86-64, version 1 (SYSV),
dynamically linked (uses shared libs), for GNU/Linux 2.6.4, stripped

Not sure if this helps or not.

-Matt
