description |
The following patch is versus 3.5, and the patch will have to be modified for 3.2. However a user has reported this problem with the 3.2 upstream kernel, so I'm sure it's in precise. See the commit description for a reproduction. Could someone running precise try running the repro and confirm you're seeing it with the precise kernel?
mke2fs -q -t ext4 -O ^flex_bg /dev/vdd 5g
mount -t ext4 /dev/vdd /mnt
fallocate -l 4600m /mnt/test
For the bug fix and any follow-on discussion, please see:
http://thread.gmane.org/gmane.comp.file-systems.ext4/32720 |
== Precise SRU Justification ==
From Ted Ts'o comment on LP bug:
"Given that many LTS users may have large RAID arrays who might not
want to copy data to do the backup / reformat / restore dance, and if
they were using ext3 and want to upgrade to ext4, they would get hit
by this, it would be great if you could get a kernel with this bug fix
pushed out with the next kernel release."
== Fix ==
The fix has been submitted upstreams here:
http://thread.gmane.org/gmane.comp.file-systems.ext4/32720
It has also been forwarded to stable.
== Impact ==
Users upgrading from ext3 to ext4 on kernels 3.2 and above will be hit
by this bug.
== Test Case ==
The following allows to trigger the bug:
mke2fs -q -t ext4 -O ^flex_bg /dev/vdd 5g
mount -t ext4 /dev/vdd /mnt
fallocate -l 4600m /mnt/test
