- PSI (reports Fabio):
- dCache: Created a working testbed SL6 dCache 1.9.5-29 + BDII, RPMs from EGI.
- dCache: Our production SL6 pools were affected by Leap second problem affects dCache on SL6 nodes!
- dCache: A 'migration cache' job can be transformed in a 'migration copy' job without to transfer again the same files. This saves time.
- Disks FW: Properly updated the FW on ~40 Seagate disks inside a Sun Fire X4540, used Oracle patch 141468-07.
- WNs: Firmware Update on the new DALCO Nodes, to be done without downtimes during July.
- UNIBE (reports Gianfranco):
- UNIGE (reports Szymon):
- Operations
- Space management picks up again, even with 310 TB in the SE and 100 TB in NFS.
- Otherwise stable.
- Upgrade
- IBM still the best deal
- Hesitating to get 64 cores/box in 2U machines we will rather get 1U machines with 32 cores.
- More cores with AMD, so go for that. We don't believe in the outstanding Intel specs.
- One machine to test first (IBM x3755 M3) planning 10.
- CVMFS
- Not yet here, 20 GB cache on disk would be a problem on some machines
- Will try CVMFS on an NFS server.
- Suggested by Andrej Filipcic.
- Interesting for more sites.
