Adding a new logical group

The add_logical_group command creates a new logical group. Parameters are specified on one line:

cmu> add_logical_group image_name "device"

For example:

cmu> add_logical_group my_logical_group "cciss/c0d0"processing 1 logical group ...Adding nodes to a logical group

The add_to_logical_group command adds nodes to a logical group. Parameters are specified on one line:

cmu> add_to_logical_group nodes to group_name

For example:

cmu> add_to_logical_group o184i115 - o184i116 to my_logical_groupselected nodes: o184i115 o184i116processing 2 nodes...Backing up a node

Backs up one node in an existing logical group. Prior to this backup, you must know the complete name of each partition you intend to back up. Two possible syntaxes are available for this command. You can specify all the parameters on one line, or use only the backup command to get an interactive backup menu:

cmu> backupor:cmu> backup "image_name" "root_partition,other_partition" node_name

You must specify the root partition before any partition. However, other partitions can be mentioned in any order.

IMPORTANT: If some partitions are omitted, then nodes which will be cloned from the image created by the backup command might not function correctly. For example, an image of a system with separate / and /boot partitions cannot be cloned successfully if you omit /boot from the list of partitions to back up.

The following example backs up three partitions on a hard disk of a node.cmu> backup "test_julien" "sda1,sda5,sda9" o185i195
