Dual-stack problem

Friday was spent adjusting the IPv4/IPv6 deployment. It was sufficient to fix the GridFTP doors to have a single dual-stack interface.

CMS production instance is now generally OK, but some (non-dCache specific) issues with network routing remain. These are being investigated.

Problematic pool

RT ticket 9372

The upgrade to the newer dCache instance is to record zookeeper interactions in the .zookeeper log file.

Unfortunately (!), after this upgrade, the problem went away and is no longer reproduceable.

Recommend upgrading all nodes to a dCache version that logs zookeeper interactions, in case the problem comes back.

Because the problem is no longer reproduceable, the ticket has been closed.
