Site reports


Elena reported that everything is more or less running smoothly.

Upgrade plans

Currently running dCache v3.1.

PIC is planning to upgrade their test instance to dCache v3.2 over the next week.

Once this has been achieved, they will schedule an upgrade to their production instance.


dCache has been running fine for the past week.


KIT are in the process of deploying IPv6 for CMS. This is the first production deployment of IPv6 at KIT.

It hasn't gone as smoothly as they had hoped, but none of the problems (so far) have been dCache related.

Disconnected pool

Xavier reminded that they still have a problem their pool

This is reported in ticket RT 9372

Paul suggested to upgrade to the latest dCache version. This includes support for the new .zookeeper logfile, which may yield information about the potential ZK problem -- or help eliminate possible problems.

CMS plugin

Xavier filed a bug against the CMS xrootd plugin. The dCache domain log file contains some trace-level logging.

This is causing the log file to become very large, with the possibility of filling up the disk by the weekend.


Christian reported that things are going fine; there's nothing to report.

Support tickets for discussion
