5.8.3 Recovering MD devices and logical volumes To recover MD devices, known as Linux Software RAID, 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.  Manually by using the mdadm and lvm utilities-see Creating the volume structure manually. 5.8.3.1 Creating the volume structure automatically Suppose that you saved the volume structure to the /etc/ASM directory 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. To create the volume structure by using the management console 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 Server OEM 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. To create the volume structure by using a script 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. Run the restoreraids.sh script, specifying the full file name of the archive-for example: /bin/restoreraids.sh smb://server/backups/linux_machine_2010_01_02_12_00_00_123D.tib 5. Return to the management console by pressing CTRL+ALT+F1, or by running the command: /bin/product 6. Click Recover, then specify the path to the archive and any other required parameters, and then click OK. If Acronis Backup & Recovery Server OEM could not create the volume structure (or if it is not present in the archive), create the structure manually.

5.8.3
Recovering MD devices and logical volumes
To recover MD devices, known as Linux Software RAID, 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.
Manually by using the
mdadm
and
lvm
utilities—see Creating the volume structure manually.
5.8.3.1
Creating the volume structure automatically
Suppose that you saved the volume structure to the
/etc/ASM
directory 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.
To create the volume structure by using the management console
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 Server OEM 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.
To create the volume structure by using a script
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.
Run the
restoreraids.sh
script, specifying the full file name of the archive—for example:
/bin/restoreraids.sh
smb://server/backups/linux_machine_2010_01_02_12_00_00_123D.tib
5.
Return to the management console by pressing CTRL+ALT+F1, or by running the command:
/bin/product
6.
Click
Recover
, then specify the path to the archive and any other required parameters, and then
click
OK
.
If Acronis Backup & Recovery Server OEM could not create the volume structure (or if it is not
present in the archive), create the structure manually.
