FIO - ELFms Meeting, 10th February 2004

Vladimir Bahyl briefly explained the structure of the /etc/sysctl.conf file. The information in the file should be kept in CDB in some format.

German Cancio pointed Vladimir Bahyl to the spma NCM component, there all necessary key/value options are defined in the profile.

Vladimir Bahyl will look into the spma NCM component and supervise Benjamin Chardi to write sysctl SPMA component.

German Cancio will deploy NCM framework on 1 development node: lxdev03. All people are advised to test their NCM components as well as all programs that use CCConfig. Wider deployment should then happen next week.

Jan van Eldik will talk to Vladimir Bahyl to agree on a reasonable list of components that should be installed on a RedHat Enterprise Server node.

None.

3)Action items :

New actions:

• [A98] Vladimir Bahyl will look into the spma NCM component and supervise Benjamin Chardi to write sysctl SPMA component.
• [A99] German Cancio will deploy NCM framework on 1 development node: lxdev03. All people are advised to test their NCM components as well ass all programs that use CCConfig.
• [A100] Jan van Eldik will talk to Vladimir Bahyl to agree on a reasonable list of components that should be installed on a RedHat Enterprise Server node.

Completed actions

• [A10] T.K. (David Hughes): The program 'check-this-host.pm' should be installed locally through RPM
  Done - RPM is deployed everywhere.
• [A11] Veronique: Put scripts in AFS C3/bin area into CVS.
  Done; but old scripts need to be moved to 'old'. Judit will update her scripts in the AFS area.
• [A58] TS & JvE: Add support for RAID in pan partition manipulation functions
  Done by Tim Smith.
• [A62] Tim/Thorsten/German: Structure the LXSERV server cluster into replicated "read-only" front end nodes serving clients and a back end node hosting the CDB
  Done in a sense that all servers serve as read-only nodes because of demand from clients. To be addressed later.
• [A84] Bill: Disk HW information should be added to CDB. Depends on [A58]
  Done by Jan van Eldik.
• [A85] German: Prepare IA64 templates for OpenLab cluster node(s), install and test quattor.
  Done - a number of minor, but time-consuming issues have been identified which would need to be addressed before being able to run SPMA and the rest of quattor on IA64.
• [A93] Vlado: DNS round-robin using service ping for SWREP alias
  SWREP.cern.ch DNS alias has been moved to the new system, functionality didn't change, but the framework now allows it.
• [A95]: Benja: enhance his maintenance script to check for an existing instance and exit if it is already running
  Done by default - check for maintenance.lock file.
• [A80] VL:  write a 'change_state' (aka "bring_me_down") script, which  will undertake the neccessary actions to bring the node to the desired state.
  Done

Stalled actions:

• [A51]: (TK): automounter SUE feature: should also start the portmapper, so that it can be disabled on nodes not needing it.
  Stalled - will be done as an NCM component for the next RH release.
• [A63] German: LCG to provide a list of services per node type, including the list of RPM's.
  Stalled - LCG provides a manual installation guide, but no service to RPM mapping.
• [A74] German: New RH release needs to be added to the Software Repository platforms
  Stalled - on hold until new RedHat version is decided, IA64 RH ES3 was added
• [A75] All: The CDB templates need to be cloned/adapted for new RH release
  Stalled - on hold until new RedHat version is decided
• [A86] TK: One new SEIL node should be added to the LXDEV cluster.
  Stalled until new batch of machines arrive

Ongoing actions:

• [A6] GCM: SWRep->CDB interfacing. Use new CDBOP
  no progress.
  [A8] T.K. was suggesting to have a file in /etc/ with some installation releated information, like the date and time of the install, and the version and release of the installed Linux. Evtl. the Serial number.
  no progress
• [A48] Tim, German: ACL feature modification needed for serial console users.
  No update.
• [A57] Judith: CASTOR CLI. For testing purposes, the corresponding SUE feature will generate a dummy shift.conf.new configuration file with real data. The CLI needs to be packaged as RPM. Real data has to be put in CDB.
  More testing to be performed before handing over to CASTOR operations team.
• [A70] TK (All): lxdev01 should be reconfigured to use the same setup as lxserv01. Thorsten to reinstall it with lxserv01 setup once lxservb01 is done.
  No progress
• [A76] Harry/Uli: Find out what is the full information needed for server nodes in LSF 5.1 (split from [A61])
  Action changed from Tim to Harry
• [A77] Piotr: implement XML API allowing pan to invoke external programs
  No update
• [A87] Bill: Create new Oracle9i based CDB SQL database.
  Some emphasis should be put into making CDB SQL interface usable (= faster) to help justify CDB as a wider deployable solution.
• [A89] GCM to write the new set_partition function that allows multiple SWAP partition
  Depends on [A58].
• [A90] Vlado: check LXBATCH SW templates division into interactive and non-interactive parts
  Discussion done, list of RPM that will be removed has been prepared, Thorsten Kleinwort will send e-mail to experiments.
• [A92] German: Provide documentation on how to manage the SPMA cache.
  German will send an e-mail where he described where we can find the documentation (man spma)
• [A94] TK: Deploy NCM on remaining clusters: LXMASTER, LXFONT, SURE (and others ?)
  Vlado deployed the NCM framework on many clusters, remaining ones: LXMASTER, LXFONT, SURE will be done by Thorsten Kleinwort.
• [A96] Bill: Implement left join on existing CDB2SQL views
  no update
• [A97] Veronique/Jan: Update/refine HostState.pl (Vero), 'sensorify' HostState.pl (Jan)
  Jan working on providing a generic command handler for sensors
