This prints out how much of the disk is free. The first line is the one we're interested in. If
the
Size
is much smaller than the size of your microSD card, you'll need to resize your
partition. Just enter the following:
root@beaglebone:/var/lib/cloud9#
cd /opt/scripts/tools/
root@beaglebone:/opt/scripts/tools#
./grow_partition.sh
root@beaglebone:/opt/scripts/tools#
reboot
root@beaglebone:/var/lib/cloud9#
df -h

This clever script will figure out how big the partition can be and grow it to that size. A
reboot is necessary.
Here, I started by putting a 4 GB image on an 8 GB microSD card. Initially, only 3.2 GB
were usable. After growing the partition, most of the card (7.2 GB) is available.
Mac
If you are running from a Mac host, the steps are fairly similar to running on a Linux host,
except that you won't be able to view the Linux partition on the created microSD card.
Begin by plugging a 4 GB or bigger microSD card into a reader on your host and then run
Disk Utility. Select the disk and click Info. In
Figure 1-29
,
you can see the Disk Identifier
is
disk1s1
.
