Description Martin Kyral 2012-07-17 11:35:02 UTC

Description of problem:
I found out that on Fedora 17, filefrag -v returns wrong extent count. In fact, the utility behaves similar as described in https://bugzilla.redhat.com/show_bug.cgi?id=653234 but the behavior is opposite now.

Version-Release number of selected component (if applicable):
e2fsprogs-1.42.3-2.fc17

How reproducible:
Always


Steps to Reproduce:
1. touch foo
2. filefrag foo
3. filefrag -v foo
  
Actual results:
0 [mkyral@localhost ~ ]$ filefrag foo
foo: 1 extent found
   ^^^^^
0 [mkyral@localhost ~ ]$ filefrag -v foo
Filesystem type is: ef53
File size of foo is 0 (0 blocks, blocksize 4096)
foo: 0 extents found
   ^^^^^


Expected results:
0 [mkyral@localhost ~ ]$ filefrag foo
foo: 1 extent found
   ^^^^^
0 [mkyral@localhost ~ ]$ filefrag -v foo
Filesystem type is: ef53
File size of foo is 0 (0 blocks, blocksize 4096)
foo: 1 extent found

Well, actually, if you simply "touch foo" then it has 0 extents.

You should get 0 in both cases...

There was a patch on the list last April, "[PATCH] E2fsprogs/filefrag: fix filefrag regression" which addressed this but never got merged.  I'll review it & ping Ted.

Thanks,
-Eric

    filefrag: fix report of number of extents

fixed this.

Present in v1.42.5; I don't really think it needs an update pushed to F17.  If you disagree, please reopen and I can do so.
