He is running PNFS v3.1.18 64-bit.

The plans for updating Tier-1 to 1.9.10 continue; starting 1st February he will start some serious testing of 1.9.10. If everything is OK by mid-to-end of February then he'll upgrade the Tier-1.

Paul to email Gerard a summary of discussion about plans for SRM linkgroup problem.


Simon reported that everything is OK with production dCache instances.

He will make some changes to improve throughput (triggered by pools becoming disabled due to PoolUp messages being not sent often enough).

Simon asked if it was possible to trace a transfer from SRM through to the door and then into the pool. He would like to monitor a single transfer.

Tigran reported that there's nothing really binding the information about a transfer in SRM and in the rest of dCache.
