October 3

Site services on the sara vobox at CERN were crashing and finally completely stopped. Pedro managed to solve it, here is an explanation and manual what to do: "MySQL was simply not working properly. It didn't accept any more connections. when the agents were running you could see the error. to fix you should stop and start the agents. when you start the agents they try to make a database connection which because MySQL is still blocking new connections (this behaviour I haven't seen before). in this case, you should login to the 'site' MySQL machine, stop and start MySQL, go back to VOBox and start the agents."

A new unscheduled downtime for SINP, since 3.10. to 10.10.

LFC server change, mu11.matrix.sara.nl -> lfc-atlas.grid.sara.nl Oracle database server and the LFC were moved from two old dual Xeon nodes to two new dual core dual CPU Xeon machines with 4GB of memory, two power supplies each and hardware RAID1 system disks.

Yesterday we managed to get a dump of files stored at tbn18 and registered at mu11. Out of 45028 files, which were not found by the first version of the script (uses the same path at LFC as for SURL with a change /dpm/nikhef.nl/home/atlas -> /grid/atlas), only 47 were not registered.

A long list of possibly corrupted files at NIKHEF. They may be corrupted due to a bad enclosure. The list contains 176931 files. A randomly chosen 3 files is a small statistics, but I got 1 corrupted and 2 not corrupted. Sizes were 79 KB, 80MB (the two non corrupted) and 100 MB (corrupted). I downloaded them, computed md5sum and compared with a value stored in the LFC.

Some sites were missing in FTS configuration file services.xml. They were inserted yesterday. Many other sites are missing since then.

dpm-qryconf shows some space on all ATLAS pools (minimum 600 GB).

ITEP:
Cleaning of ITEP continues. A provided list of files (20 156 files) present at ITEP at 28.01.2007 did not help: some files were there twice. 4323 files were not known to LFC, 16193 had no replica at ITEP, so these cannot be unregistered.

I did a complete "integrity" check. I identified 38590 missing files in ITEP and now I ran lcg-uf to delete them from the catalogue. It is very slow, I hope that tomorrow it will be cleaned.
