automatically assembled following the reboot. To view or change the partition type, use a disk

partitioning utility such as fdisk.

 Otherwise (such as in the second example), perform the recovery from bootable media. No

reboot will be required in that case. In bootable media, you may need to create the MD device

manually or automatically, as described in Recovering MD devices and logical volumes (p. 38).

3.5.2.5 Recovering MD devices and logical volumes

Recovering MD devices and/or volumes created by Logical Volume Manager (logical volumes)

assumes that the corresponding volume structure will be re-created.

In Linux-based bootable media, you can create the volume structure automatically (p. 38) when

recovering the volumes from:

 A backup created by Acronis Backup & Recovery 11.

 A backup created by Acronis Backup & Recovery 10, provided that the volume structure

information was saved in the backup. (It is saved by default.)

In other cases, before starting the recovery, you need to create the volume structure manually (p.

38) by using the mdadm and lvm utilities.

Creating the volume structure automatically

Use the following procedure to create the volume structure in a Linux-based bootable media.

Note: If you are recovering the volumes from a backup created by Acronis Backup & Recovery 10, this procedure

works only if the volume structure information was saved in the backup. (It is saved by default.)

Caution: As a result of the following procedure, the current volume structure on the machine will be replaced

with the one stored in the archive. This will destroy the data that is currently stored on some or all of the

machine's hard disks.

If disk configuration has changed. An MD device or a logical volume resides on one or more disks,

each of its own size. If you replaced any of these disks between backup and recovery (or if you are

recovering the volumes to a different machine), make sure that the new disk configuration includes

enough disks whose sizes are at least those of the original disks.

To create the volume structure automatically

1. Boot the machine from a Linux-based bootable media.

2. Click Acronis Bootable Agent. Then, click Run management console.

3. In the management console, click Recover.

Under the archive contents, Acronis Backup & Recovery 11 will display a message saying that it

detected information about the volume structure.

4. Click Details in the area with that message.

5. Review the volume structure, and then click Apply RAID/LVM to create it.

Creating the volume structure manually

The following is 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.
