Description
The LHCb experiment operates a large computing infrastructure with
more than 2000 servers, 300 virtual machines and 400 embedded systems.
Many of the systems are operated diskless from NFS or iSCSI
root-volumes. They are connected by more than 200 switches and
routers. We have recently completed the migration of the management of
this system from Quattor to puppet and of the original monitoring
structure based on Icinga to icinga2. We also have a tight integration
of icinga2 in puppet. In this paper we present challenges and
experiences during this migration. We discuss and contrast the
expected and observed operational improvements.
