FIO - ELFms Meeting, 2nd March 2004

German gave a presentation about his tests on using proxy servers for the LXSERV cluster. His presentation can be found here.

German presented a first outline of the porting issues of CEL3. A transparency can be found here. The two main points are:

1. Get all tools ready for CEL3 by the end of March: spma, Kickstartgenerator, etc.
2. Get all NCM components written by the end of April, to have a machine in LXPLUS and LXBATCH ready for the users

Therefore we need at least one, better three test machines for us (FIO) running CEL3

German has agreed to give a tutorial about who to write NCM components and how to use quattor build tools.

In addition everybody is asked to have a look into the other three documents:

1. FIO Tools: Tools written/used by FIO for configuration/installation/monitoring
2. SUE to NCM migration plan Plan listing all SUE features that have to migrate to NCM components
3. Lemon List of monitoring metrics that have to tested on CEL3

In particular, the maintainers for 1) and 2) should be reviewed and changed, if necessary. Please keep in mind that every item in 1), 2) and 3) needs eventually a name assigned to it. We will have to agree on these names in the upcoming ELFms meetings.

A test machine from Linux Support is available: lxcert-i386

1. Porting CCConfig outside SUE: To have a better control over releases of CCConfig, it was agreed to take it out of the SUE RPM and therefore become more independent of SUE releases for CCconfig releases. In addition, there will be no SUE in CEL3.  It was as well agreed that this should  be back ported to RH7.3. The implementation details of how this is going to be achieved should be left for the maintainer
2. The issue about local users, that was brought up by Jan van Eldik a week ago and ansered by Vlado should be discussed in one of the next meetings, because Vlado was not around.

4) Action items :

New actions:

• [A101] All: Review list of maintainers for FIO tools and SUE to NCM migration

Completed actions:

• [A74] German: New RH release needs to be added to the Software Repository platforms
  CEL3 was added
• [A89] GCM to write the new set_partition function that allows multiple SWAP partition
  Done
• [A92] German: Provide documentation on how to manage the SPMA cache.
  Done and used for last kernel upgrade
• [A94] TK: Deploy NCM on remaining clusters: LXMASTER, LXFONT, SURE (and others ?)
  Done
• [A97] Veronique/Jan: Update/refine HostState.pl (Vero), 'sensorify' HostState.pl (Jan)
  Done
• [A98] Vladimir Bahyl will look into the spma NCM component and supervise Benjamin Chardi to write sysctl SPMA component.
  Done
• [A99] 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.
  Done

Stalled actions:

• [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.
  [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.
• [A77] Piotr: implement XML API allowing pan to invoke external programs
  No update: Piotr left, should somebody take over?

Ongoing actions:

• [A6] GCM: SWRep->CDB interfacing. Use new CDBOP
  no progress.
• [A48] Tim, German: ACL feature modification needed for serial console users.
  No update: Needs sombody assigned to the task to do it
• [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.
  Should be finished soon, to be checked with JN
• [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: LXDEV01 is still in use by Benjamin and Bill. To be checked if this can be done on lxdev05
• [A76] Harry: Find out what is the full information needed for server nodes in LSF 5.1 (split from [A61])
  Action changed from Tim to Harry
• [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.
• [A90] Miro: check LXBATCH SW templates division into interactive and non-interactive parts
  Miro has taken over, list is prepared
• [A96] Bill: Implement left join on existing CDB2SQL views
  no update
• [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.

Next Meeting: Next week, 09.03.2003
