Trying to create a basic ext4 filesystem:

Code:

# mke2fs -b 1024 -cc -L /boot -N 1024 -m 0 -n -O ^dir_index,^dir_nlink,extents.^extra_isize,^flex_bg,^has_journal,^huge_file,^uninit_bg -t ext4 -v /dev/sda5
mke2fs 1.42.7 (21-Jan-2013)
Invalid filesystem option set: ^dir_index,^dir_nlink,extents.^extra_isize,^flex_bg,^has_journal,^huge_file,^uninit_bg


OK, trial and error finally led to a conclusion (still don't understand why). It only works if extents is the LAST feature (it did not used to be that way):

Code:

# mke2fs -b 1024 -cc -L /boot -N 1024 -m 0 -n -O ^dir_index,^dir_nlink,^extra_isize,^flex_bg,^has_journal,^huge_file,^uninit_bg,extents -t ext4 -v /dev/sda5
mke2fs 1.42.7 (21-Jan-2013)
fs_types for mke2fs.conf resolution: 'ext4', 'small'

[...]


Things like this don't exactly fill me with confidence. Any thoughts?

Edited to remove some (but not all) of the superfluous stupidity.

Is this the actual command you used? There is a period instead of comma after extents.

Please see /etc/mke2fs.conf, too.

That would explain it.

I was actually looking for that (not a comma), and staring right at it, but I didn't see it.

Guess that is telling me I need stronger lenses. :(
