Add new testcases for ext4 new features - V3

This is the patch of testcases for the ext4 new features test. It contains multi-block alloc/delayed alloc test, inode version test, journal checksumming test, nanosec timestamps test, online defrag test, persist prealloc test, subdirectory limit test and uninit groups test of ext4.

In this test suite, there is two FAIL in the subdirectory limit test. It is because we cann't create more than 32000 subdirectory when block size is small, such as 1024, and the name of every subdirectory is very long, such as every name is 255 bytes. I think it is the bug of the ext4.

Note: Your MUST run configure in the directory
testcases/kernel/fs/ext4-new-features
to config the tool of ffsb, and specify a partition to be used for
test
before compiling the tool. The data on the specified partition
would be
DESTROYED.

Hi, Mr.Subrata

The patch that you made to fix the problem of ffsb was not merged into this patch. So if you want to run this testcases, you must applied your patch before compiling the testcases.

Regards.

Is this a known issue for EXT4 ?

Creating many long filenames (255 bytes) in a 1kB block filesystem is a known issue that is not expected to be fixed (at least I'm not aware of any work being done in this area). A vast majority of filesystems today are formatted with 4kB blocks (due to disk size) and the overhead of
managing 1kB block filesystems makes these only marginally used, and it is also very rare to have applications with such large filenames.

And the good news continues. I did a complete run of the tests this time. Unlike last time where it was running for more than 48 hours owing to huge FS size(680GB), i ran it on a small 135GB partition this time. It took around 40 hours completing the entire run which also include the online-defrag tests. Guess, the new Code Coverage results are:

Lines: 56.1%,
Functions: 66.4%,

However, it is also accompanied by the following failures in the online-defrag part:

Miao,

Did you see these failure on your machine ?

Some more points are:

1. Can you please run these tests against the backdrop of the Makefile changes in LTP to see all the build/install/run are executing fine,

2. Can you also please put all the utilities version info at the

        beginning of the test rather than printing them again and
        again(like mke2fs 1.41.9 (22-Aug-2009),tune2fs 1.41.9
        (22-Aug-2009),dumpe2fs 1.41.9 (22-Aug-2009),dumpe2fs 1.41.9

Is this a known issue for EXT4 ?

Quoted 7 lines

Creating many long filenames (255 bytes) in a 1kB block filesystem is a known issue that is not expected to be fixed (at least I'm not aware of any work being done in this area). A vast majority of filesystems today are formatted with 4kB blocks (due to disk size) and the overhead of
managing 1kB block filesystems makes these only marginally used, and it is also very rare to have applications with such large filenames.

Ok.

Quoted 6 lines

Quoted 4 lines

We also uncovered that the tests gives a decent 50% lines and over 61% function coverage for EXT4 code. Please find the individual coverage under EXT4 attached.

Interesting to see this.

And the good news continues. I did a complete run of the tests this time. Unlike last time where it was running for more than 48 hours owing to huge FS size(680GB), i ran it on a small 135GB partition this time. It took around 40 hours completing the entire run which also include the online-defrag tests. Guess, the new Code Coverage results are:

Lines: 56.1%,
Functions: 66.4%,

However, it is also accompanied by the following failures in the online-defrag part:

Miao,

Did you see these failure on your machine ?

Your take on this ?

Quoted 5 lines

Some more points are:

1. Can you please run these tests against the backdrop of the Makefile changes in LTP to see all the build/install/run are executing fine,

Could you please verify this before this release. Let me know a patch if you find any discrepancy :-)

Quoted 5 lines

2. Can you also please put all the utilities version info at the

        beginning of the test rather than printing them again and
        again(like mke2fs 1.41.9 (22-Aug-2009),tune2fs 1.41.9
        (22-Aug-2009),dumpe2fs 1.41.9 (22-Aug-2009),dumpe2fs 1.41.9
        (22-Aug-2009))

This can go in the next month release as well, if you do not have time to fix now. Else, i have a bug mouth to eat this as well ;-)

Your take on this ?

I didn't find these failure on my box.
The attached patch opens the verbose mode of e4defrag to get more information later, it is useful to find the problem of online defrag.
So, Could you test it again and send the output info to me?

This patch can fix the following problem:
-- delete the code of setting the test_fs flag

-- throw the utilities version info away

/dev/VG1_EXT4/LV1_EXT4: The test_fs flag is set (and ext4 is available).
CLEARED.

You don't need to set the test_fs flag for modern ext4.

Can we change this ?

The attached patch can fix this problem.

I had already checked in your earlier patch long back. So, you would please need to resend over the latest code.

I had already checked in your earlier patch long back. So, you would please need to resend over the latest code.

I'm sorry that I didn't bring the new patch(was sent on 2009-11-30) to your attention, so I resend that new patch now. I have tried to apply the patch to the latest code in the cvs repository and everything is ok.

Subrata, I didn't find these failure about online defrag on my box.
The attached patch opens the verbose mode of e4defrag to get more information later, it is useful to find the problem of online defrag. So, Could you test it again and send the output info to me?

The following is changelog.
=========================
This patch can fix the following problem:
-- delete the code of setting the test_fs flag
-- open the verbose mode of e4defrag, it is useful to find the problem of online defrag -- fix some bug of the Makefile
-- throw the utilities version info away
-- delete two unnecessary testcases about ext4 subdir limit test

/dev/VG1_EXT4/LV1_EXT4: The test_fs flag is set (and ext4 is available).
CLEARED.

You don't need to set the test_fs flag for modern ext4.

Can we change this ?

The attached patch can fix this problem.

I had already checked in your earlier patch long back. So, you would please need to resend over the latest code.

I'm sorry that I didn't bring the new patch(was sent on 2009-11-30) to your attention, so I resend that new patch now. I have tried to apply the patch to the latest code in the cvs repository and everything is ok.

Subrata, I didn't find these failure about online defrag on my box.
The attached patch opens the verbose mode of e4defrag to get more information later, it is useful to find the problem of online defrag. So, Could you test it again and send the output info to me?

The following is changelog.
=========================
This patch can fix the following problem:
-- delete the code of setting the test_fs flag
-- open the verbose mode of e4defrag, it is useful to find the problem of online defrag -- fix some bug of the Makefile
-- throw the utilities version info away
-- delete two unnecessary testcases about ext4 subdir limit test
