What you can do as a workaround is use the relevant tool to remove
the ext3 features that parted doesn't like, resize, and then add them
back in.
Off the top of my head,
debugfs (use 'help' and 'features').
??? doesn't like journal or hashed directory indexes
Sorry I don't recall the exact specifics, I recommend you check the
details before you do anything (and don't forget that backup !)
The exact details are surprisingly hard to google up quickly, although
I expect they feature prominently in a HOWTO or FAQ somewhere. Simply
improving the error message would be a huge step: google turns up large
numbers of people stumped by this error message.
