Operational blog posts

Could still do more blog posts, e.g. workshop (Sam), "UKT0" (Jens)

RFIO will be deprecated for DPM - maybe within ~1yr, so need to migrate away. Use DAV instead.

Report from the DPM workshop

Sam reporting. There were site reports from IT, FR, UK, AU. Common topics included slow drains and deletions, leading to a general discussion on the best approach.  Also the ATLAS data consistency check.

Everybody else happy with puppet. YAIM is not being updated any more and cannot be used for 1.8.9/10. Instructions for people's own config (ie manual) available. Ansible was mentioned. There is no additional effort but DPM will support.

Instead of RFIO there will be a REST interface.

ITDSS at CERN IT manages EOS, CASTOR - if they also support DPM they will have three different storage "solutions"

HTTP (anonymous, non-SRM) support, but not enabled by default. Accounting does not know about SRM

GridFTP redirection in 1.8.10 but only with a client with delayed PASV, e.g. GFAL2; will not work with uberftp or g-u-c. Fallback to extra internal copy.

dpm-db tool: new version promised.

ELK log parsing, needs packaging [also used by CASTOR team at RAL.]

The LFC was used by Belle2; no patches for 3 years (!?).

Possible to move head node: French sites did this.

Update on the ATLAS issues from last week

Testing. Edinburgh problem - wrong hostname. Otherwise testing uploading the catalogue - how is the file copied in? John B wrote his own script.

Highlights and Lowlights reports from the past year (in case someone should feel inspired to write a blog post about them?!)

(see blog...)

Merry and Happy

Someone's mic is picking up female speaking, SAm is that you?

Jens Jensen: (10:06 AM)

Yes, it's Sam's

Paige Winslowe Lacesso: (10:07 AM)

Sam, can hardly make out what you're saying, background female voice is overriding yours

Jens Jensen: (10:09 AM)

RFIO is the oldest part of DPM :-/

Just like SRM and its TURLs :-)

Tom Whyntie: (10:25 AM)

The Wiki pages, right ;-)

elena: (10:30 AM)

Sam, I put the ticket in "waiting to reply" status and incolved atlas ddm support. If They didn't check it by the end of today I'll send them a reminder by email.

Ewan Mac Mahon: (10:35 AM)

it's tricky - mostly I've left the storage alone this year.

Matt Doidge: (10:35 AM)

That could be a highlight

Ewan Mac Mahon: (10:35 AM)

The interesting next question will be whether to upgrade all the YAIM/SL5 nodes to puppet/SL6, puppet/SL7 or something else.

But clearly it's about time to move them to something.

Samuel Cadellin Skipsey: (10:36 AM)

puppet/SL7, if you can wait for 1.8.11

Ewan Mac Mahon: (10:36 AM)

When's that likely to be?

Matt Doidge: (10:36 AM)

I'm still planning to upgrade all my Sl5 nodes to a skip.

Samuel Cadellin Skipsey: (10:36 AM)

(which will actually be 1.9.0)

Paige Winslowe Lacesso: (10:36 AM)

THANKS JENS!

Tom Whyntie: (10:36 AM)

Bye! Merry Chrimbo all!

Samuel Cadellin Skipsey: (10:36 AM)

In Janurary, probably, Ewan
