Arg. File > 2GB removal

Arg. File > 2GB removal

[Damacus Porteng]

For grins, I did `dd if=/dev/zero of=testfile bs=1024 count=4000000` 

Obviously, with the limits of ext2, this isn't allowed, however, dd continued
marrily on its way, tho it spouted an error...

I cancelled the dd and went to remove the file, though the following occured:
root@obfuscated:/home/ftp# rm testfile
rm: cannot remove `testfile': Value too large for defined data type     

'ls' complains about the same.  I ran e2fsck -f /dev/hde6 (the partition of
/home) and it didn't 'find' the problem.

How do I remove this file and reclaim the HDD space?

Thanks,

D.

you don't mention which kernel you are using, but for some time now
ext2fs has been able to handle large files (>2GB) -- and I suspect dd
created such a beast for you

rm probably stat'd the file beforing removing it -- and failed,
because it's either old or uses and old library (which isn't LFS
aware)

If that's true, then the following C programlet should remove the file:

Replace "huge-file-name" with the full path of your file, it needs to stay
in quotes.

---

#include <stdio.h>
#include <stdlib.h>

int main()
{
  unlink("huge-file-name");
  return 0;
}

Oh no!  This is linux-kernel.  I thought it was debian-user.  Sorry,
didn't mean to waste bandwidth :}

Hrm... This is with 2.2.18:

[18:17:15] hogarth@theirongiant:/data>> dd if=/dev/zero of=testfile bs=1024 count=4000000
dd: testfile: File too large
2097152+0 records in
2097151+0 records out
[18:21:07] hogarth@theirongiant:/data>> rm testfile
[18:24:16] hogarth@theirongiant:/data>> 

So it worked for me... Regardless though have you tried

>testfile
rm testfile

?

With 2.4 it's allowed.

You need an rm that's using the LFS interface.

Try:
echo > testfile
