SUMMARY

If the installable UB /backups partition was created as a Linux LVM, it can be expanded.

ISSUE

For Installable UB (OnMetal) systems, they are allocated a certain amount of storage at install time based on the size of the /backups partition.   If the /backups partition was created as a Linux LVM, it can be expanded.

RESOLUTION

The following requires the administrator be knowledgeable in Linux and LVMs.

To expand backup storage for Installable UB:

1. Add additional storage for the /backups partition.  If adding internal disks, shutdown the system.
2. Bring down the Unitrends software so there is no activity on the disk:

   /etc/init.d/bp_rcscript stop

3. Expand the LVM mounted as /backups to include the new storage (e.g. using Linux commands pvcreate, vgextend, lvextend, and xfs_growfs).
4. Start the Unitrends software again:

   /etc/init.d/bp_rcscript start

5. Download the device size update script:

   wget ftp://ftp.unitrends.com/utilities/update_metal_size.sh

6. Update the D2D device size in the database:

   sh update_metal_size.sh

NOTES

The "update_metal_size" script will detect the size of the /backups partition, do a little math, and apply that to the D2DBackups device which resides on /backups.  This script will only make changes if the new size is larger than before.
