Resolution

The issue is related to the method used to copy the $JENKINS_HOME from one location to another one.

Best option, it is to rollback to a security copy of your previous $JENKINS_HOME and copy it in the new location using a method which preserve the symlinks.

If this is not possible, to fix the master where you have these erroneous directories here is what you should do:

# Logon on the master where you have the issue
ssh machine
# Shutdown the jenkins master (take care that nothing is running)
sudo service jenkins stop
# Find all erroneous directories
find /opt/jenkins/jobs -type d \( -name "last*Build" -o -name "lastStable" -o -name "lastSuccessful" \)
# Review the list of erroneous directories
# Rename them
find /opt/jenkins/jobs -type d \( -name "last*Build" -o -name "lastStable" -o -name "lastSuccessful" \) -exec mv {} {}.err \;
# Restart jenkins
sudo service jenkins start
In the future you can delete these directory if everything is fine with

In the future you can delete these directory if everything is fine with:

# Delete them
find /opt/jenkins/jobs -type d -name "*.err" -exec rm -rf {} \;

You should do a security copy of your $JENKINS_HOME before trying the method described above.
