Sites meeting

 

James Perry

 

Working on  configuration  to make it more configurable

Moving experiment-specific stuff to external packages

 

What about site-specific—there are changes in latest version that ought to help with them.

What we really need is QOS stuff

——

Checksum mismatches

 

Steve noticed 2 dual phase files which hadn’t shown as transfer to tape, these turn out 

To be checksum mismatches we will have to resend.

Nersc running

 

Failure in the metadata extractor that looks like a timeout but might not be.

If the metadata extractor fails it doesn’t copy the file to the local NERSC

 

Could take out the part that does the declaration.

 

——

 

NP02 data at IN2P3—was run 1265 copied there?  Yes but it appears it was not declared to SAM.

 

 

——

 

FTS3/Rucio at NERSC

Non-CMS FTS3 server at FNAL in progress but not likely to be ready soon.  May be able

To use fts3.fnal.gov (CMS owned) for testing purposes.  Needed to get the Nersc-generated

MC back to Fermilab.
