Bug#685726: ext4 bug for kernel linux-image-3.2.0-4-amd64 (3.2.39-2).

[hrayr@infotech.am]

Today I have upgraded the kernel, now it is linux-image-3.2.0-4-amd64
(3.2.39-2).
I think we have to reopen the bug, because it seems that the bug is not
solved but just suppressed the warning messages.
It is not just my thoughts; everyone can make sure executing couple of
command.



df     ( will show the free space of partition, f.x. 200GB free)

dd /dev/zero of=IMG_FILE bs=1M count=128k    (will create image file, with
size 128GB)

df     ( now we can see that the partition free space is 72GB, because we
have 128GB image file on it)

mkfs -t ext4 IMG_FILE        (will format image file, without any error
messages or warnings!!!)

df     ( after the formatting process is finished, "df" will show that we
have 200GB free space, and "ls -al" will show that we also have file
IMG_FILE on the partition, with the size 128GB!!!)



This effect is exactly the same as it was before, but with one small
difference: the error messages suppressed, and we haven't chance to see
errors.
It is worst. We have the bug, but haven't error messages.


Please take into account that I haven?t created the "sparse" file, in the
case of "sparse file" it is normal when you have 128 GB file on 200 GB
partition and the command "df" is show that 200 GB is still free.
