Airwave backup recovery when the server is non boot-able due to corrupted OS image.

This article will help to explain how to recover server backup when the Airwave server fails to boot.


Since Airwave run's on CentOS 5.5 / 6.2 operating system, we can use the live boot-able disk when the server fails to boot due to issue with detecting OS image from server harddrive.

Note: If that bad hard drives partition "/dev/mapper/VolGroup00-LogVol00" is not mountable then we would be able to fetch the backup from the server.


Environment : Airwave server would not boot if there is any kernel panic issue or if an issue with Hard drive node [0,0] and fails to detect Operating System Image.


Download the CentOS 5.5 / 6.2 x64 live bootable image, refer the following URL for CentOS live image.

>    Burn the image to the disk and boot the server with the image.

>     Once you reach the "#" prompt make sure you have network connectivity and able to reach available network storage.

>    Run the following mkdir command create a mounting point "temp" and the command followed by to mount the logical volume on the server to access the disk.

# mkdir /mount/temp
# mount /dev/mapper/VolGroup00-LogVol00 /mount/temp
# cd /mount/temp

>    Run the below scp command to copy nightly backup file and license from the server hard drive to the network storage.

# scp /mount/temp/var/airwave-backup/nightly_data001.tar.gz <username>@<>:</some/remote/directory>
# scp /mount/temp/var/airwave/license/license.txt <username>@<>:</some/remote/directory>

>    Rebuild the Airwave server using the same version ISO image as the defective server version using the installation guide available in the following URL

>    Once the server was rebuild copy the backup nightly_data001.tar.gz file to /tmp directory using winscp tool.

>    Run the following command to restore the backup.
    # screen
    # root
    # amp_restore -d /tmp/nightly_data001.tar.gz



once the backup is restored we can login to webUI of Airwave to verify the data that we restored from the backup
