Hi Esa,

The ext3 resize code is really pretty experimental. It may be that it's
not properly dealing with a valid ext3 fs here (which would explain why
e2fsck doesn't find a problem but parted chokes). We could try to figure
out what is wrong here - a dumpe2fs log or an e2image of the affected
file system might contain enough data to debug this (the dumpe2fs output
will be fairly small and compresses well. The e2image data would be much
larger even when compressed since it records all the metadata from the
file system).

If this file system has any important data that's not backed up then you
might prefer to do the resize using the resize2fs tool. This is provided
in e2fsprogs and has been around longer and had more testing coverage
than the ext3 resizing code in parted.

Regards,
Bryn.
