5.8.3.2 Creating the volume structure manually
The following are a general procedure for recovering MD devices and logical volumes by using a
Linux-based bootable media, and an example of such recovery. You can use a similar procedure in
Linux.
To recover MD devices and logical volumes
1. Boot the machine from a Linux-based bootable media.
2. Click Acronis Bootable Agent . Then, click Run management console .
3. On the toolbar, click Actions , and then click Start shell . Alternatively, you can press
CTRL+ALT+F2.
4. Create the volume structure according to that in the archive, by using the mdadm utility (for MD
devices), the lvm utility (for logical volumes), or both.
Note: Logical Volume Manager utilities such as pvcreate and vgcreate , which are normally available in
Linux, are not included in the bootable media environment, so you need to use the lvm utility with a
corresponding command: lvm pvcreate , lvm vgcreate , etc.
5. Return to the management console by pressing CTRL+ALT+F1, or by running the command:
/bin/product
(Do not reboot the machine at this point. Otherwise, you will have to create the volume
structure again.)
6. Click Recover , then specify the path to the archive and any other required parameters, and then
click OK .
Example
Suppose that you previously performed a disk backup of a machine with the following disk
configuration:

The machine has two 1-gigabyte and two 2-gigabyte SCSI hard disks, mounted on /dev/sda ,
/dev/sdb , /dev/sdc , and /dev/sdd , respectively.
 The first and second pairs of hard disks are configured as two MD devices, both in the RAID-1
configuration, and are mounted on
/dev/md0 and /dev/md1 , respectively.

A logical volume is based on the two MD devices and is mounted on
/dev/my_volgroup/my_logvol .
The following picture illustrates this configuration.
Do the following to recover data from this archive.
