Summary of meeting:
Present: Fraser (Edinburgh)
Owen, Jens (RAL)
David, Steve (RAL, able to join only later)
Not present: anyone else
Status and update:
Glasgow now has 4 TB storage, of which 2.5 reachable from the
Grid. They're NFS mounted on LCG SE ("classic"). Hoping to
deploy dCache.
Fraser mentioned there will be changes at Edinburgh; Steve Thorn
(another "Steve T"!) will be leaving for NeSC (not very far..?)
Question about the general lifecycle of the file on the Grid.
There are several known and largely unsolved issues, in particular,
how it is written from the WN off into permanenter storage (SEs).
Also the question of space reservation on WNs was raised last week
at the AHM. Open. (In fact, that's part of what we're aiming to
solve in GridPP2 in the Storage Mware group.)
Connected question regarding whether RFIO clients are avaliable
on WNs, for transferring the data into mass storage systems and SEs.
Steve T confirmed that it was available (at least via GFAL but then
GFAL calls the RFIO libraries); in LCG SE, rfiod is switched on by
default.
However, current version of GFAL, 1.3.8, is very broken (doesn't parse
SURLs), unlike the previous one, 1.3.7, which was broken only in
more subtle ways (segfaulted if request status not "Ready" on first
getRequestStatus, IIRC). Current version has been broken for some
time, and it has been reported in Savannah.
Finally, we're looking for people who are going to CHEP because we
believe there will be interesting storage talks in general, and
Don Petravick's in particular. We believe the next issues will
be network and transfer between SEs. In contrast, the *control*
protocol stuff goes on in the GGF context. Owen and Jens will
go to GGF12.
Which brings me to remind people who have read this far that there
will be no telconf on 22 Sep because it coincides with GGF. The
next telconf will be held on 6 Oct.
Thanks,
--jens
