<-- keep this as a security measure:
   #uncomment if the subject should only be modifiable by the listed groups  
  • Set ALLOWTOPICCHANGE = TWikiAdminGroup,Main.CMSAdminGroup
  • Set ALLOWTOPICRENAME = TWikiAdminGroup,Main.CMSAdminGroup #uncomment this if you want the page only be viewable by the listed groups # * Set ALLOWTOPICVIEW = TWikiAdminGroup,Main.CMSAdminGroup

Node Type: WNsSuperMicro

Firewall requirements

local port open to reason

<-- Example line
 #| 22/tcp      | * |  Example entry for ssh |

Regular Maintenance work

Nagios

check UIs on t3nagios

User quota on /tmp /scratch ( but not super important )

When a new T3 user is created you have to run on each UI :
<--/twistyPlugin twikiMakeVisibleInline-->
# kinit -k -t /root/afs-keytabs/svcusr-t3_puppet.keytab svcusr-t3_puppet@D.PSI.CH && aklog && ls -l /afs/psi.ch/service/linux/puppet/var/puppet/environments/DerekDevelopment/manifests && puppet apply --environment DerekDevelopment /afs/psi.ch/service/linux/puppet/var/puppet/environments/DerekDevelopment/manifests --modulepath=/afs/psi.ch/service/linux/puppet/var/puppet/environments/DerekDevelopment/modules --show_diff --color=false

Emergency Measures

<--
 #List any measures that must be taken in case of some major incident, e.g. whether a mailing
 #list must be contacted or whether other services need to be shut down, etc. 
-->

The WNs servers run on the top of a mdadm raid10, so they can survive to 1 broken disk ; to repair online the broken disk simply adapt this procedure NodeTypeWNsIntelS2600JF#Degraded_RAID1_or_Failed_RAID0 to these servers. Generally speaking all the mdadm operations apply.

Installation

<--
 #Comment here on any peculiarities of the installation, e.g. on special packages needed, special setup
 #procedures which are not obvious
-->
Because of the mdadm raid10 we should never get to the point where a reinstallation is needed ; anyhow the Puppet recipes are in /afs/psi.ch/service/linux/puppet/var/puppet/environments/DerekDevelopment/manifests :
  • SL6_wn.pp
  • SL6.pp
  • tier3-baseclasses.pp
  • and the partition/raid10 layouts are /afs/psi.ch/software/linux/dist/scientific/66/x86_64/custom/tier3/t3wn/ks-partition.cfg
