Re: Resizing GPT partitions
There is a good software can solve your problem--Partition Manager. You needn't worry about anything wrong at all; it can help you easily http://www.extend-partition.com/help/how-to-resize-partition.html resize partition without data loss. And I want to tell you, this software is free for use. So, I think this is your best choice. -- View this message in context: http://old.nabble.com/Resizing-GPT-partitions-tp28820639p29488441.html Sent from the freebsd-stable mailing list archive at Nabble.com. ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org

You can try to download snapshot of livefs CD of 9.0-CURRENT and use it. http://pub.allbsd.org/FreeBSD-snapshots/ Well, it's becoming too complicated for me. I'll try another approach : installaing the system in the swap partition, boot on that, make the other partition, install the system, boot on the right partition, delete the first one and use it as a real swap.
