FIO - ELFms Meeting, 2nd March 2004
- Present: German Cancio, Benjamin Chardi, Jan van Eldik, Thorsten
Kleinwort, Helge Meinhard, Harry Renshall, Tim Smith
- Minutes: Thorsten Kleinwort
1) Proxy deployment on
head nodes and LXSERV
German gave a presentation about his tests on using proxy servers for the
LXSERV cluster. His presentation can be found
here.
The agreement was to go ahead with the solutiuon to have proxy server on all
headnodes. The installation, including the burn in tests, should go ahead to
deploy this solution soon. We don't have to wait until the cables for the serial
consoles have arrived.
In addtion, we should consider to equip the LXSERV front end servers with
gigabit network cards.
2) CEL3 porting issues
German presented a first outline of the porting issues of
CEL3. A transparency can be found
here. The two main points are:
- Get all tools ready for CEL3 by the end of March: spma,
Kickstartgenerator, etc.
- 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:
-
FIO Tools: Tools written/used by FIO for
configuration/installation/monitoring
-
SUE to NCM migration plan Plan listing all SUE features that have to
migrate to NCM components
-
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
3) AOB:
- 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
- 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:
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.
