Creating The Volume Structure Manually - ACRONIS BACKUP AND RECOVERY 10 SERVER FOR LINUX - UPDATE 3 User Manual

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. If necessary, examine the structure of volumes which are stored in the archive, by using the
trueimagecmd utility. Also, you can use the trueimagemnt utility to mount one or more of these
volumes as if they were regular volumes (see "Mounting backup volumes" later in this topic).
5. 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.
6. If you previously mounted the backup by using the trueimagemnt utility, use this utility again to
unmount the backup (see "Mounting backup volumes" later in this topic).
7. 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.)
8. Click Recover, then specify the path to the archive and any other required parameters, and then
click OK.
Note: This procedure does not work when connected to Acronis Backup & Recovery 10 Bootable Agent
remotely, because the command shell is not available in this case.
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.
