Summary: e2fsck -fD on ext4 breaks
Product: File System
Version: 2.5
Kernel Version: 2.6.32.10
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1

i did a e2fsck -fD on a ext4 filesystem, later a e2fsck -f complains a bunch of errors. if i e2fsck -fy would end up a bunch of files go into lost+found or simply lose trace.
Step to reproduce:
1. prepare a ext4 file system (dd if=/dev/zero of=test_ext4.img bs=1M count=1000 && mkfs.ext4 test_ext4.img)
2. mount it (mount -t ext4 -o rw,loop test_ext4.img /mnt/tmp)
3. put some files on it, it seems to me that tiny files would cause the issue (cp -r /home/$USER/.gconf /mnt/tmp)
4. un mount it (umount /mnt/tmp)
5. e2fsck -f test_ext4.img all good
6. e2fsck -fD test_ext4.img seems fine
7. e2fsck -f test_ext4.img here comes trouble...

Regression|Yes |No--- Comment #2 from Theodore Tso <[email protected]> 2010-04-01 11:50:10 --- This isn't a kernel bug (and this is a bugzilla for tracking kernel problems).
This was a bug in e2fsprogs 1.41.10, which was fixed in e2fsprogs 1.41.11.
I suggest you upgrade, and I apologize for the inconvenience. In general data
isn't lost, although files and directories do get dropped into the lost+found directory, and cleaning up can be a bit of a mess.
Best regards,
-- Ted
