Check_MK Werk 5204: Host rename: Fixed broken rename of hosts in rrdcached journal

ID: 5204 Title: Host rename: Fixed broken rename of hosts in rrdcached journal Component: Core & setup Level: 1 Class: Bug fix Version: 1.5.0i1 When using the new Check_MK rrd format (single value per RRD), the host rename feature was not renaming host specific entries in the journal of the rrdcached. This resulted in lost RRD values that have not been written to the RRDs yet. Manual fix: You could stop the rrdcached (or the whole site), go to var/rrdcached and rename the host in the journal files manually, e.g. using <tt>sed</tt>.
