Hello,
I installed a FreeBSD 8.0-RELEASE into a virtual machine (with virtual
box), using a GTP partitioning scheme, and zfs. The virtual disk disk
is 10 Go.
I dumped this disk image to a real machine, which has a 160 Go disk.
The system works fine, but I can only use 10 Go of disk space. How can
I gain more space ?
How can I enlarge the last partition of the disk to use the whole disk ?
I tried to create a new partition on the disk, and planned to add it
in the zfs pool, but that didn't work :
# gpart add -t freebsd-zfs -l disk0f ad0
gpart: autofill: No space left on device
That's odd, because it seems that gpart is aware of the new geometry.
What's the problem ?

GPT holds information about first and last usable sectors. You can see them in your output:> last: 20971486 > first: 34You can look at freebsd-geom's mail list archive. There was a topic "OCE and GPT" with similar problem. -- WBR, Andrey V. Elsukov -------------- next part -------------- A non-text attachment was scrubbed...

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.
