SQL functions

Tigran still promised to comment on the SQL functions.

AP/ Paul to remind Tigran.

ATLAS delayed/slow deletions

Issue last week -- deletions from ATLAS

88 files -- all requested to be deleted in the same hour; 37 hours.

No pool was offline.

none of the 88 hours were accessed during the period.

only 3 were accessed right before the deletion came in.

RT ticket 9043.

CMS regression

Updated dCache for cms from 2.13.9 to 2.13.44

transfers.txt file -- different characters all '-' and ' ' are escaped in HTML.

RT to follow.


transfers.html equivalent -- python tool

Validates fine with HTML -- door mover includes html entity unknown occurrences invalid HTML -- not escaped.

RT ticket to follow.


Everything is OK at PIC. Everything is running smoothly.

Experiment interested to know which files have been accessed in the past n years. So they can send data to tape.

IN2P3 analysised previously presented.

For old PNFS-ID (from PNFS), inodes table, but


Ulf reported things are going quite well.

ATLAS users got unhappy over the weekend. Since Friday, anything created in their NDGF SCRATCH disk has directories with permissions 664.

Paul reported this as a known bug, that is already fixed.

NDGF has a downtime on Thursday, so would be able to do upgrade then.

Since Ulf is away, Mattias will be doing the upgrade.

dCache slowing down

Ulf reported that he should have more machines in a week to test this further.
