Description Richard W.M. Jones 2014-05-21 08:22:06 EDT
Description of problem:

mke2fs on Rawhide (but not Fedora 20) has started to fail on i686

/usr/sbin/mke2fs -t ext2 -Fq '/tmp/tmp.8XawRF2EgH/d2.0ryxonke/root
Could not open /tmp/tmp.8XawRF2EgH/d2.0ryxonke/root: Value too large for defined data type

The size of the file is 4GB exactly.

This FAQ suggests that this error is because the utility has
been compiled incorrectly:

Note that this does not fail on x86-64, nor on Fedora 20, nor
on earlier versions of Rawhide.  The failure has started in the
last few days.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Create 4GB file.
2. mke2fs -t ext2 -Fq file

Cripes, did e2fsprogs lose -D_FILE_OFFSET_BITS=64 / O_LARGEFILE stuff?  Bleah, I'll look into it.
Comment 2 Eric Sandeen 2014-05-21 13:22:20 EDT
It's a regression, this should fix it.

Comment 3 Eric Sandeen 2014-05-21 13:50:26 EDT
actually, using ext2fs_open_file() is probably better.

Anyway, fix building for rawhide.

Thanks for the report!

I have verified this fixes the problem for me, thanks.
