CPK

Service interruptions

A CPK is C&CZ’s way of reporting a problem or service interruption. Follow the mailing list or RSS feed, and check the service interruptions page for live status updates.

A CPK is how C&CZ reports a problem or service interruption. We publish one when something goes wrong, when we need to do planned maintenance, or when we want to let you know about something that affects the services we run.

Note

What’s a CPK? CPK is short for the Dutch C&CZ Probleem Kaart — C&CZ problem card. The name is simply how we’ve always done it, and it has stuck with us ever since.

How to follow CPK messages

CPK messages are first sent to the CPK mailing list — you can (un)subscribe there. You can also follow the service interruption messages via RSS.

When a CPK takes longer to resolve, we publish updates on the service interruptions page.

University-wide interruptions

CPK#1082 Print/phpMyAdmin server replacement Thursday April 17 08:30-09:20

Because of the recent problems with this server, we are going to replace the server, in order to prevent further service interruptions.

CPK#1081 U:/ home server pile problem

The server had a problem with one partition, which had started during the creation of new snapshots. We waited with the reboot untill after working hours. A reboot of the machine solved the problem. To prevent these problems in the future, we will no longer make local snapshots of homeservers, but of course the daily backups of the homeservers by the backup server will be continued.

CPK#1080 And yet again Print/phpMyAdmin server problem

Just like four days ago, the server didn’t react for unknown reasons. A reboot of the machine solved the problem. We plan to replace the server next Thursday 08:30-09:00 hours, in order to prevent further service interruptions.

CPK#1079 Again Print/phpMyAdmin server problem

Just like two weeks ago, the server didn’t react for unknown reasons. A reboot of the machine solved the problem. Together with the supplier we will try to find out what to replace to prevent this in the future.

CPK#1078 U: / home server bundle problems

From the moment of yesterday’s snapshots (13:00 hours), more and more processes were hung at the server. The first complaints arrived at C&CZ ca. 11:15 hours this morning. Therefore we decided ca. 11:35 to restart the server. The reboot resolved the problem. The number of snapshots will be reduced in order to try to prevent problems due to snapshots in the future.

CPK#1077 Printer pr-hg-00-002 did not print from Windows/Mac

Probably due to a too large printjob, the printer queue on the server (printto/printsmb/ooievaar) for the pr-hg-00-002 printer got stuck onWednesday morning. C&CZ was only informed of this problem at the end of Thursday. Friday morning this has been fixed by emptying the printqueue with old jobs.

CPK#1076 Print/phpMyAdmin server problem

The server didn’t react for unknown reasons. A reboot of the machine solved the problem.

CPK#1074 U:/ home server pile problem

The server had a problem with one partition. A reboot of the machine solved the problem.

CPK#1075 Linux login server lilo3 reboot due to NFS-problems

The Linux login server lilo3 didn’t have the homedirectories of some users. It took a reboot to fix this.

CPK#1073 File server heap problems

The fileserver failed to start after the Monday morning reboot, because of filesystem errors (LVmd2-7). Manually fixing the errors solved the problem and the machine started successfully.
