Deploying a File Recovery Enabler for Linux with Nutanix Acropolis Hypervisor (AHV) Cluster

A File Recovery Enabler for Linux (FREL) enables instance data to be browsed from a backup for the source instance, with support for ext2, ext3, ext4, XFS, JFS, HFS, HFS Plus, and Btrfs file systems. Use the QCOW2 template supplied by Commvault to create an instance that contains the File Recovery Enabler.

Note

  • The File Recovery Enabler for Linux package is deployed as a MediaAgent in restore-only mode, and does not consume a license. The client does not appear in the Client Computers list unless the Show Unlicensed with software (Restore only Clients) option is selected in User Preferences.

  • Live browse and file recovery operations are not supported for XFS realtime subvolumes.

  • Live browse and recovery is supported for subvolumes of Btrfs file systems.

Before You Begin

  • Before creating an instance for Linux file restores, install the latest available service pack for Commvault on the CommServe host and Virtual Server Agent (VSA).

  • Use the latest available version of the File Recovery Enabler template. The template version must match the installed service pack version.

  • The File Recovery Enabler must be deployed on the same Nutanix AHV cluster cloud. Optionally, you can reconfigure the File Recovery Enabler to act as a VSA proxy, in which case the File Recovery Enabler consumes a Virtual Server license.

Procedure

  1. On the Cloud Services website, go to the Commvault Store and download the Nutanix FREL Image with 11.20 n package for the installed service pack (for example, SP20) to a location that is accessible from the Nutanix AHV cluster.

  2. Go to https:// < cluster-IP-or-FQDN > :9440/console/#page/settings/acropolis_image, and then upload the image to the Nutanix AHV cluster.

    A new task is launched.

  3. Check whether the new task is complete at https:// < cluster-IP-or-FQDN > :9440/console/#page/tasks.

  4. Go to VMs page, click Create VM, and then use the following configuration:

    • 1 CPU

    • 1 core/CPU

    • 4GB RAM

    • 1 NIC

  5. Add a disk and select option Clone from Image Service.

  6. Select Custom Script.

  7. In the Type Or Paste Script, paste the following:

     
    CS_IP_OR_FQDN=commserve_host
     
    CS_SHORT_NAME=commserve_client_name
     
    CS_USERNAME=user_name
     
    CS_PASSWORD=password
     
    FREL_CLIENTNAME=client_name
     
    ROOT_PASSWORD=password

    Note

    The user name must have both Global > Administrative Management and Commcell > Install Client permissions.

  8. Click Save.

    A new VM is launched and registered to the CommServe.

  9. Configure a default File Recovery Enabler for Linux to use for UNIX-based file restores as described in Specifying the Default File Recovery Enabler for Linux for a Virtual Server Instance.

  10. You can login to FREL with root account using password given in the script. Once logged in, you can enable root access by modifying /etc/ssh/sshd_config to allow root login (PermitRootLogin yes) and or to allow password authentication (PasswordAuthentication yes), and then restarting ssh services. To use password authentication for root, perform the following steps:

    $ sudo su

    # passwd (enter new password for root)

Note

If you still experience connection issues after deployment, you can also add fully qualified host names and IP addresses for the File Recovery Enabler and the CommServe system to the /etc/hosts files for both machines to ensure that both systems can resolve host names locally.
