LVMDriver : Failed to create LVM Instance

Challenge

In RHEL 7.4, Veeam Agent for Linux operations such as job runs or job creation are failing with the following error:

LVMDriver : Failed to create LVM Instance

Cause

With RHEL 7.4, the default global unit setting in the /etc/lvm/lvm.conf changed from 

units = "h"

to

units = "r"

This value option is not recognized by some distributions and programs. It interferes with the operations of Veeam Agent for Linux.

Solution

Before implementing this change, please check with your Linux Administrator that they approve of updating the global unit setting from “r” to another value. You can find a full list of available unit options at this RHEL link.

More Information

If the lvm.conf file doesn’t show a units value of “r”, please open a support case for further investigation.
