[parted-devel] parted failed to increase ext3 partition

[Andreas Hirczy]

Hi!

  I already entered this in the bug tracking, but it never showed on
  bug-parted at gnu.org; cant check in bug tracking system since all interesting
  links from <http://parted.alioth.debian.org/cgi-bin/trac.cgi/report> lead
  to "Trac detected an internal error:"

I tried to increase an ext3 partition from 1583GB/3091307625s to nearly 2
TBytes and failed. Tried with parted version 1.7.1 (Debian stable),
1.8.7.git.2007.07.30 (Backport from Debian unstable) and 1.8.8 (compiled from
last tar.bz2).

The file system is pretty full (~85 %) and is hosted on a 3Ware Raid
controller; all disks are reported as fully correct.

Here is a transcript of my actions:

No error message, but the size of partition 4 did not change.

Thanks,
