new E-Log

FacOps has enabled our e-log in the official place
https://lxbra1907.cern.ch/elog/Analysis+Operations/
it has no RSS feed, but people can subscribe to get mails of postings. I think we should switch to use that. THat way anyone in CMS (e.g. Computing shifter) can post. If you do not have already an e-log password you will need to register, I am using same username and password as Hypernews, to keep it simple. I will make an attempt at importing history from blog there, but if it does not work right-away, I'll give up.
See you on the new logbook.

put back slc5cern=vocms21 in AvailableServerList

Fabio fixed the problem http://savannah.cern.ch/bugs/?66389 one test task went OK, status from web OK, also some users where submitting anyhow (guess they hardcoded slc5ern in their crab.cfg) and it all looks normal. Stefano

how to add/remove a Crab server etc.

our operation twiki now has instructions on how to use crab config files to e.g. add/remove one crab server to pool. The TWISTY thing I put is maybe not so nice, feel free to edit.

today's news

slc5cern aka vocms21 is still unusable, Fabio is looking at it, seems it just takes it an awful amount of time to go through backlog and Fabio is looking into speeding that up. Is an interesting thing and we are not in a hurry, so let' keep it off the available list.
CMSSW_370 is breaking crab compatibility (something changed in FWCore), details in Savannah.
Mistery of "file already exists but i am sure directory was empty" deepens.

Reply all is default

I have made reply all the default for the feedback list - makes it easier not to forget to do reply all when replying to messages as I often forget. Found this in the "labs" part of the settings for the gmail when looking for statistical tools.

Cheers,
Dave

vocms21 removed

I commented out slc5cern (i.e. vocms21.cern.ch) in /afs/cern.ch/cms/LCG/crab/config/AvailableServerList
(and committed change to CVS). Stefano

restarted again

was stuck again. Restarted a couple of times. But still left with a bunch of jobs in Submitting state. Do not know what do, will leave for developers to investigate.

CrabServerWorker component restarted



vocms21 were not submitting (noticed after user complained). I restarted CrabServerWorker as per instructions https://twiki.cern.ch/twiki/bin/view/CMS/CrabServerOpsIssues#Down_Component and things seem recovered. Details for developers in Savannah https://savannah.cern.ch/bugs/index.php?66389 . Image from http://vocms21.cern.ch:8888/graphjobstcum/?length=24&span=hours show that activity was stopped then restarted. Stefano
