Create cron job which reconnect drive with jboss-nexus-public-jboss repository

There is network drive mounted to the Nexus where the "jboss-nexus-public-jboss" repository is stored. Time to time drive is disconnected and repository becomes unavailable. Then Jenkins jobs are failing until somebody reconnect the drive. It will be fine to have this process automated.

We need something like this:

if /dev/vdb is not mounted on /home/hudson/repo then
sudo mount /dev/vdb /home/hudson/repo
service nexus restart
