Line: 1 to 1
  • Hardware Prerequisite:
    • 1 dedicated host (it could be both virtual or physical) to install Wnodes Nameserver
    • A repository for the Virtual Machine images
Line: 20 to 20
        • and define "QUEUENAME_GROUP_ENABLE" equal to the VO that will be enable to the specific queue (where "QUEUENAME" is the name of the queue)
        • Reconfigure the CE with YAIM
  • Step Needed:
    • Create a IP/DNS for each virtual node that will be created (1bait + n Virtual WN per real Node)
    • Create a IP/DNS for each virtual node that will be created (1bait + n Virtual WN, per real Node)
      • the hostname for the bait host should contain "bait" (e.g.: bait-wnodes-XX)
      • the hostname for the virtual node should contain "vm" (e.g.: vm-wnodes-XX)
    • Install a single nameserver:
      • yum install wnodes_manager-1.0.0-2.noarch.rpm wnodes_nameserver-1.2.2-3.noarch.rpm wnodes_utils-1.1.5-3.noarch.rpm
      • configure file: /var/log/wnodes/nameserver/wnodes_ns_state and /etc/wnodes/nameserver/wnodes_hv_config.ini /etc/wnodes/nameserver/wnodes_bait_config.ini
Line: 28 to 30
    • Configure the new nodes on the torque server editing the file /var/spool/pbs/server_priv/nodes like the following (where the first node i a standard node farm, the sencond is an example of a bait and the third is a virtual node that will run the jobs):
      • wn01.cnaf.infn.it np=2 lcgpro
      • bait-tf-01.cnaf.infn.it np=2 cloudtf bait
      • vwn-tf-01.cnaf.infn.it np=1 vwn-tf-01
      • vn-tf-01.cnaf.infn.it np=1 vn-tf-01
        • the properties are really important and should be configured as in the example
    • edit di configuration files and configure the images for both using YAIM in order to customize the images for you site
    • Create a dedicated queue for wnodes jobs:
      • For examples using: qmgr -c < queue_command :
