Undeletable files

[Roland Bock]

Hi,

an e2fsck-run left a few files sprinkled over the file system which seem 
to be undeletable. Although the FS is mounted RW, even root does not 
seem to be able to delete them.

None of these files can be deleted or modified. None of the user/group 
IDs is valid. Root cannot change any of the attributes.

For example:
#: rm 20011112_0000_AAM_TUI_000.txt
rm: cannot remove `20011112_0000_AAM_TUI_000.txt': Operation not permitted

#: chown root:root 20051109_0000_AAM_TUI_000.txt
chown: changing ownership of `20051109_0000_AAM_TUI_000.txt': Operation 
not permitted

#: chmod a+w 20061221_0000_AAM_TUI_001.txt
chmod: changing permissions of `20061221_0000_AAM_TUI_001.txt': 
Operation not permitted


Any idea of how to get rid of these files? I have about a 100 million 
files on that file system. "About" 30.000 are in such a state as 
described above. The rest behaves normally (can be modified, deleted, etc).


Thanks in advance,

Roland
