Comment 3 for bug 956038

Similarly with online resizing:

$ cp tiny xxl
$ dd if=/dev/zero of=xxl bs=1 count=0 seek=1310720M
$ sudo losetup /dev/loop0 xxl
$ sudo e2fsck /dev/loop0
e2fsck 1.42 (29-Nov-2011)
/dev/loop0: clean, 11/65536 files, 12635/262144 blocks
$ sudo mount /dev/loop0 /mnt
$ sudo resize2fs /dev/loop0
resize2fs 1.42 (29-Nov-2011)
Filesystem at /dev/loop0 is mounted on /mnt; on-line resizing required
old_desc_blocks = 1, new_desc_blocks = 80
Performing an on-line resize of /dev/loop0 to 335544320 (4k) blocks.
resize2fs: Operation not permitted While trying to add group #8192

$ sudo umount /dev/loop0
$ sudo e2fsck /dev/loop0
e2fsck 1.42 (29-Nov-2011)
/dev/loop0: clean, 11/67108864 files, 4220121/268435456 blocks

With online resizing the filesystem fails to a consistent state at the maximum filesystem size.
