===== Captain's log =====

Here I am keeping trace of the work I am doing on the cluster, for everybody to track progress.

The logs can be read top to bottom from the most recent change to the newest.

 --- //[[:Florido Paganelli]] 2014/02/21 10:26//
  * installed and configured arc. Job sumbission with emi-es a failure, but maybe ARC 4.1 will solve all.
  * configured arc with slurm and cache; however would be better to have two grid users (one for each division) and two queues.

 --- //[[:Florido Paganelli]] 2014/02/18 13:55//
  * installed salt on arc-iridium
  * installed other trustanchors on arc-iridium

 --- //[[Florido Paganelli]] 2013/08/07 17:31//

  * added information on how to install autofs and cernvmfs on the [[iridium_cluster:wantedpackagesonnodes]] page

    * changed firewall to enable squid proxy access
    * created atlas.sh script on n2 to enable atlas environment.

  * Configured frontend kvm-iridium machine networking to be ready for hosting.

==== Fixmes ====
FIXME FIXME FIXME FIXME FIXME

I decided to collect FIXME s here because it was difficult to track them down when spread across logs.

  * <del>autofs is mounting everything as nobody:nobody user as if it was all_squash set. Check how to solve. SOme say is idmap</del> solved by setting NIS domain name to iridium and having storage-iridium joining the NIS domain. I guess nis domain names are forwarded from nfs4 to clients.
  * document squid setup better! especially custom selinux modules.
  * squid proxy access should be limited to nodes
  * Optionally install a second failover squid on service-iridium.
  * better iptables configuration on all nodes and servers based on ''-m state'' rules. Done on
    * //iridium//
    * //storage-iridium//
    * //kvm-iridium// (complex due to kvm)
    * //service-iridium// only for tcp connections. Check what to do for udp.
  * check xfs selinux rules on //storage-iridium//, added with chcon might disappear :( probably needs module creation as squid.
  * Mixed config for NFS3/NFS4. Would be better to use nfs4 and limit portmapper to NIS.
  * needs stronger authorization check on portmap/rpcbind services (i.e. hosts.allow on all machines) to be done in NIS SALT
  * <del>update page [[iridium_cluster:wantedpackagesonnodes]] with current salt configuration.</del>
  * generation and distribution of host keys on the nodes at deployment time is needed. Might be done as Luis did for SALT.
  * change default user groups in the cluster for all users and in documentation
  * investigate on-demand vm creation
  * change NIS passwd change system. disable yppaswd on all nodes. For the moment being shut down yppasswdd on service.
  * salt should check if a group is installed. This will speedup things.
  * sort out why dhcp won't renew after trying for long time.
  * add CA certificates to all machines. Probably storage server to share certs would do the trick and need only one crl check in place.
  * define a proper time when node update
  * disable cvmfs autoupdate
  * salt-minion do not restart after upgrade. Find means to force it. salt-command might jam if done that way: <code>salt -v 'n5.iridium' cmd.run "service salt-minion restart"</code>
