Site reports

NDGF

Things are very hectic at NDGF at the moment.

Jens reported how NDGF are busy scripting their dCache system using ANSIble.

The upgrade of NDGF to dCache v3.2 is scheduled for Monday (2018-06-18), with some work ongoing this week on testing this.

Some small issues with the chimera command have been found; Jens will open a ticket describing this issue.

PIC

Elena reported that PIC have upgraded all their systems to dCache v3.2 and they are running perfectly, with no problems.

PIC wanted to have a webdav door that supports uploads. PIC already has WebDAV doors, but they are only for downloading data.

She described how there seemed to be a problem uploading large files, resulting in files failing randomly.

Messages suggested a timeout issue with dCache internal communication, when sending messages to space-manager.

These messages were seen before the upgrade to dCache v3.2, so it isn't clear if the problem is due to the upgrade.

WebDAV door is configured to redirect clients to the pool and there is a DNS round-robin, targeting 6 WebDAV doors.

Elena will open a ticket describing this problem.
