The new e2fsck 1.43.4 (31-Jan-2017) has definitely helped, but I'm
still seeing some flakiness with inline_data directories. There's still
a kernel problem, which is creating file systems that confuse e2fsck.
But I have more data on the e2fsck problem which is mis-correcting that
problem so it takes a second run to get a clean file system.
Specifically, e2fsck is creating the missing system.date problem on one
run and then zeroing out the directory on another.
The problem is occurring when I rsync to a small directory. Consider
the following directories:
1461410 (12) . 1421827 (12) .. 1461583 (20) potd-800.jpg
1472133 (36) .xvpics 1461401 (72) .potd-800.jpg.4176
1461314 (12) . 1421827 (12) .. 1461426 (20) potd-800.jpg
1463943 (36) .xvpics 1461400 (72) .potd-800.jpg.4176
During the rsync run, I got syslog complaints:
[255031.626936] EXT4-fs warning (device md3): ext4_dirent_csum_verify:352: inode #1461410: comm find: No space for directory leaf checksum. Please run e2fsck -D.
[255031.626940] EXT4-fs error (device md3): ext4_readdir:198: inode #1461410: comm find: path $PATH1: directory fails checksum at offset 0
[255035.720542] EXT4-fs warning (device md3): ext4_dirent_csum_verify:352: inode #1461314: comm find: No space for directory leaf checksum. Please run e2fsck -D.
[255035.720547] EXT4-fs error (device md3): ext4_readdir:198: inode #1461314: comm find: path $PATH2: directory fails checksum at offset 0
The inline data consists of two parts: 60 bytes in the block pointers which
hold the first four entries, and 72 bytes in an ea, which holds the fifth and
last entry.
debugfs on the directories reveals the following:

If I run e2fsck on that stat, it complains about two things:
Inode 1461314, i_blocks is 8, should be 0. Fix<y>? yes
Inode 1461410, i_blocks is 8, should be 0. Fix<y>? yes
i_file_acl for inode 1461314 ($PATH2) is 1496383488, should be zero.
Clear<y>? yes
i_file_acl for inode 1461410 ($PATH1) is 1496481792, should be zero.
Clear<y>? yes
I don't really understand how those two errors were created in the
first place.
However, after saying yes to those, the system.data ea is missing and the
final entries in each directory get dropped, leading to being dumped
in loat+found.
Here's the state after the first e2fsck run completes:

This then leads to a second run complaining about
Inode 1461314 has INLINE_DATA_FL flag but extended attribute not found. Truncate<y>?
If I instead fix it by "ea_set -f /dev/null <1461314> system.data", I get the
directory back in a relatively unbroken state. But why is system.data
being deleted in the first place?
Add the original inline data author Zheng Liu <[email protected]>.

Hello Andreas,
Thanks for letting me know this.
Hello George,
I have tried to create a ext4 file system with inline_data feature,
and try to create a directory hierarchy like you described in the
mail. But unfortunately I couldn't reproduce your issue. That would
be great if you could provide more details to me, such as the output
of the following command.
$ debugfs ${DEV} -R 'stats'
>From this command I can know which features are enabled in your ext4
file system and that would help me to reproduce the problem. Further,
could you please tell me your kernel version?

It seems that the space is full in inline data and the kernel could not
expand it to a new block. From the following message I guess during
this process kernel tries to allocate a new block for this directory
and then an error is encountered that causes flags 0x10000000 could not
have a chance to be cleared. So this inode has flag 0x10000000 and
blockcount is 8.

^^^^^^^^^^^^^^^^^
It means that this directory contains inline data

^^^^^^^^^^^^^
It seems that this directory is currupted because a directory with
inline data should be 0. That is why e2fsck wants to fix this issue
in first round.
I will take a closer look at this problem later, and thanks for
reporting this.

Hello,
You can quite easily create a directory with inline_data and an not zero block
count.
Just create a directory and set on it several posix ACL (40 in my case for a 512
bytes inode).
Then you get something like:
Inode: 12 Type: directory Mode: 0775 Flags: 0x10000000
Generation: 3148309105 Version: 0x00000000:00000006
User: 1000 Group: 1000 Project: 0 Size: 384
File ACL: 7978 Directory ACL: 0

Size of extra inode fields: 32
Extended attributes:
system.data (324)
system.posix_acl_access (340)
Size of inline data: 384
This does not seems an error and in my case e2fsck does not complain.
Both inline data content and ACL block are correct.
So perhaps is there something else wrong in George's case. Perhaps getting block
1496481792 content could help to check if it has some ACL header or not.
Regards,
Damien
PS: I got some error on George's domain so add to remove it from recipient, hope
he could seen it on the list and this one was no sent twice
