I have faced the same issue and question. Connecting some dots I could fix my Jenkins after I moved Jenkins to a new location due to the same issue -space in disk under /var/lib/jenkins.

Here is the procedures that I had to follow to get it working taking in consideration that I am pointing Jenkins to a non-default port. (I have applied this process into 2 servers)

First, move the Jenkins directory from /var/lib/jenkins to /opt/jenkins

sudo service jenkins stop
sudo mv /var/lib/jenkins /opt/

Now you can change your workspace and build directory to any other location on your machine. Jenkins provides 3 predefined variables that can be used to specify the new location:

JENKINS_HOME — Jenkins home directory

ITEM_ROOTDIR — Root directory of a job for which the workspace is allocated

ITEM_FULLNAME — ‘/’-separated job name, like “foo/bar”

sudo su jenkins (access as Jenkins user)
JENKINS_HOME=/opt/jenkins
ITEM_ROOTDIR=/opt/jenkins
ITEM_FULLNAME=/opt/jenkins
exit (exit Jenkins user)

Now, edit the jenkins config

/opt/jenkins$ sudo nano /etc/default/jenkins

Modify the following line

#jenkins home location
#JENKINS_HOME=/var/lib/$NAME (here is the default)
JENKINS_HOME=/opt/jenkins (that is our new location)

change the home directory of a user

sudo usermod -d /opt/jenkins/ jenkins
sudo service jenkins start
