Title:
fallocate followed by mke2fs of file image causes ext4_error
Status in linux package in Ubuntu:
Invalid
Bug description:
Reported by user on linux-ext4 mailing list.
http://thread.gmane.org/gmane.comp.file-systems.ext4/33573
Easily reproduction. Create a scratch file system which is 220g
large, and mount it. Then in that scratch file system, execute the
commands:
# fallocate -l 215g file1
# mke2fs -t ext4 -F file1
The kernel will report that scratch file system has errors, but if you
run e2fsck on the scratch file system, no problems can be found.
This problem does *not* occur on the latest 3.5 kernel with the
patches pushed to Linus for the 3.6 merge window. I have not had time
to try to narrow down which commit is the fix, but I figured I would
file this bug in the hopes that someone on the Ubuntu kernel team
would have time.... (doing this sort of thing, i.e., backporting
fixes to a stable kernel, is, after all, a distribution function. :-)
