Duplicating SD Cards for Beagleboard

The ASU Linux User’s group is building a Beagleboard cluster. This requires each compute node to have an identical system image, with the exception of the hostname and ipaddress. The easiest way, I found to do this, is to configure one compute node, then duplicate the SD cards across the other nodes. Here is how I did that.

Save the partitions to an image file using part image

partimage save /dev/sdb1 beagle-cluster-boot.000 beagleboard-cluster-boot.000
partimage save /dev/sdb2 beagle-cluster-boot.000 beagleboard-cluster-rootfs.000

Save the partitions table to a file

sudo sfdisk -d /dev/sdb > beagleboard-cluster-partitions.sfdisk

Eject the card, and put in a blank card.

Unmount the partitions

umount /dev/sdb2
umount /dev/sdb1

Copy the partition table to the new card

sudo sfdisk --force /dev/sdb < beagleboard-cluster-partitions.sfdisk

Copy the partition images to the new card

sudo partimage restore /dev/sdb1 beagleboard-cluster-boot.000
sudo partimage restore /dev/sdb2 beagleboard-cluster-rootfs.000
sync
