Hi All,
As we noted last week, some people are away at the supercomputing conference
this week so we will not have a live meeting. I do have some questions for
various people that hopefully can be answered by email...
Andy:
o Did you fix some dates to come to CERN?
Fabrizio:
o Remi posted something in the BaBar HN:
http://babar-hn.slac.stanford.edu:5090/HyperNews/get/KanSOS/491.html
about the remaining issues for using the xrootd/olbd production output
buffer. The outstanding issues appear to be:
o setting the unix permissions correctly
o checksum doesn't work (might be server side config issue, see
my response in HN)
o file deletion doesn't seem to work
o Could you summarize the other things (TXNetFile cleanup, refresh bug,
etc.) that are outstanding?
Gerri/Fons:
o Gerri mentioned something to me about some backward compability issue/bug
with the original rootd. Was that understood?
o Has anything else come up in (Alice) testing of xrootd?
o We realized that we really should try to get asynchronous mode working
before the next production ROOT release (in particular the one that will
be used with POOL) since it is required to start using unsolicited
responses. The problem is that if there are lots of clients out there
which are not running in asynchronous mode, it creates a significant
backward compatibility problem since they block when such a response
comes in. Fabrizio found that it works in the posix-like client, but
there is some issue with TThread/TSocket that causes problems for
TXNetFile.
Wilko:
o Which machines at SLAC have the server-side monitoring turned on?
Jacek:
o What is the setup of the server side monitoring at SLAC? You now have
the final collector machine? Have you had a chance to look at the data?
Tofigh:
o Do we have the file access summary webpages yet?
Gregory:
o I see you are posting lots of detailed questions. Could you summarize
for us more generally how things stand for using xrootd/olbd at Cornell?
Anybody else who has something interesting to tell us should of course feel
free to follow up to this posting!
I'll make a new development build later today, too. Hopefully I'll be
able to include the MacOSX build from this point on. I've also updated a bit
more the problem page.
thanks,
Pete
