[Gluster-devel] Encountered "Directory not empty" error during remove a directory in .trashcan

[Deng ShaoHui]

Hi:

Recently I encountered an error msg "Directory not empty" during I execute
"rm -rf" command in .trashcan.
I used glusterfs 3.7.6.

Here is my reproducer:

1. I created a volume titled "eee", then I turned the "features.trash" on.

2. Mount it on /volume/eee

3. Extract a package, let's say "php-5.6.19.tar.gz". And then I delete
itimmediately.
[root at cosmo eee]# ls -a
.  ..  php-5.6.19  php-5.6.19.tar.gz  .trashcan
[root at cosmo eee]# rm -rf php-5.6.19
[root at cosmo eee]# ls -a
.  ..  php-5.6.19.tar.gz  .trashcan

4. I could find it in .trashcan path.
[root at cosmo .trashcan]# ls
internal_op  php-5.6.19

5. I intend to delete them in .trashcan.
[root at cosmo .trashcan]# rm -rf php-5.6.19/
rm: cannot remove `php-5.6.19/Zend/tests/generators': Directory not empty
rm: cannot remove `php-5.6.19/Zend/tests/constants/fixtures/folder4':
Directory not empty
rm: cannot remove `php-5.6.19/Zend/tests/constants/fixtures/folder3':
Directory not empty
rm: cannot remove `php-5.6.19/Zend/tests/traits': Directory not empty
rm: cannot remove `php-5.6.19/ext/odbc': Directory not empty
rm: cannot remove `php-5.6.19/ext/gettext/tests/locale/en': Directory not empty
rm: cannot remove `php-5.6.19/ext/simplexml': Directory not empty
rm: cannot remove `php-5.6.19/ext/curl/tests': Directory not empty

6. I checked every directory in this mount point, it seems like they
all are empty. But I jumped into bricks directory which is used by
this volume, I found these directorys, they are not empty, still hold
some files in there.


Is there anyone hit this issues before? Or I mistake some steps?
Thank you.
