OK, in reading the btrfs wiki more, resize the filesystem does not affect the size of the actual partition. Looks like I need to do that first. Will have to dig out a gparted cd, or perhaps a opensuse install dvd.
Why not calling cfdisk from inside the running system?
You intend to make the existing partition bigger. I don't see how you could harm the system by this.
1st save the current partition layout to a file.
Next you open cfdisk as root user and delete the partition you intend to extend.
3rd you create the new partition with the same starting point but with the new, bigger size.
Keep in mind this only works if there is free space left behind the partition you intend to enlarge.
Have I done this myself before? Yes.
Does the system still work? Yes
Nevertehless I suggest to do this first with a virtual machine.
This worked great! Thanks. I had to swallow hard before deleting the partition. But cfdisk next created a new one that used all the space on that drive. Then ran...
btrfs filesystem resize max /
and I've got a larger partition, all working fine.
Nice little utility.
