6.10.5. Recovering MD devices and logical volumes

To recover Linux Software RAID devices, known as MD devices, and/or devices created by Logical
Volume Manager (LVM), known as logical volumes, you need to create the corresponding volume
structure before starting the recovery.
You can create the volume structure in either of the following ways:
•
Automatically in Linux-based bootable media by using the management console or a script—see
Creating the volume structure automatically (p. 187).
•
Manually by using the lvm utility—see Creating the volume structure manually (p. 188).
6.10.5.1. Creating the volume structure automatically
Suppose that you saved the volume structure to the /etc/Acronis directory—see Backing up LVM
volumes (Linux)—and that the volume with this directory is included in the archive.
To recreate the volume structure in Linux-based bootable media, use either of the methods described
below.
Caution: As a result of the following procedures, 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.
