Linux - NBD fails to compile for CentOS/RHEL/Oracle 7.3 -
Description
When trying to install the Rapid Recovery agent on CentOS / Rhel / Oracle 7.3 you get an error when trying to compile the NBD kernel module:
cat /var/lib/dkms/nbd/3.10.0/build/make.log:

Resolution
This issue has been resolved in the latest release of Rapid Recovery
CentOS/Red Hat/Oracle 7.3 are not supported in Rapid Recovery 6.1.1 and older due to NBD not being able to compile.
That being said this issue will not affect your backups and you can still protect your machine. However, what this issue does affect is File Restores and Rollbacks to CentOS / Red Hat / Oracle 7.3 machines.
You can still restore files from another agent that is not running 7.3 and you can still perform BMR's and virtual exports without issue.
