Site reports


No problems; everything running fine.

Currently upgrading to 2.13.50 and PostgreSQL 9.5

Plan to upgrade to 2.16 on January.


No issues for the last week -- nothing to report.

No concrete plans for upgrading to 2.16; other tasks have higher priority.


We have had two issues:

  1. ALICE have been trying to overload dCache -- 490 MiB file, 50 TiB in one day. 40GiB NIC, 40 GiB switch, to 2x 10GiB to CERN.
  1. Running 3.0.2 on head nodes; upgrade from 3.0. without any down-time. One head-node; changed 24 GiB --> 12 GiB, dCache runs fine but billing needs more memory when querying, so currently draining to allow an upgrade.

Started upgrading pool nodes to CentOS 7.3, so upgrading dCache to 3.0.x at the same time.

Support tickets for discussion
