E.g. btrfsctl -r -4000m /dev/sda5

Hey Mikael,

btrfsctl is deprecated, you should use btrfs
In the previous example:
btrfs filesystem resize -4000m /dev/sda5

Check the help of btrfs

And also good to download latest btrfs-progs from git and compile them
yourself the version of btrfs-progs on LiveCD is old.


Latest version I use for example is: v0.19-35-g1b444cd

results in:
ioctl:: Inappropriate ioctl for device

Distribution: Ubuntu 10.10
Kernel: 2.6.35-22-generic

According to the Synaptic Package manager, the version of btrfs-tools=

 is

0.19+20100601-3

Other information that can be of interest:
- I started Ubuntu on a live CD
- before invoking the btrfsctl command I invoked apt-get update.

I have googled but have not found anything that seems to help me.

I have searched for "resize" on the following pages but have not find
anything:

https://btrfs.wiki.kernel.org/index.php/Gotchas

Thanks,

Mikael
