Operation problems

gdss750 failed due to fsprobe errors and was removed from production

gdss651 (preProd) is still down RT177006

Complication with the renewal of the Gen SRM host certificates due to the need to include the alternative hostnames for the different VOs in each certificate. This requires talking to Jens before the approval of the ceritificate request. Whenever a new VO is added to Gen, the certificates need to be re-issued.

gdss784 does not appear on ganglia with its host name but with its IP
