I think I'm not understanding something fundamental about btrfs: what am I
able to resize? Resizing would be nice, given that it's so hard to do
with ext3 (or even LVM).
I created a btrfs filesystem on my 32G thumbdrive (/dev/sdb):
mkfs.btrfs /dev/sdb1
To mount it, I do:
mkdir /mnt/btrfs
mount -t btrfs /dev/sdb1 /mnt/btrfs
BUT, what's the point of resizing the filesystem with something like:
btrfsctl -r 15g /mnt/btrfs
???
After I do it, I'm assuming that there's roughly 17G in /dev/sdb1 that I'm
not using, but I don't know how to get to it. Can I make *another*
filesystem on /dev/sdb1 and then mount it to somewhere like /mnt/btrfs2.
Thanks,
Charlie
