Service Interruptions

1440: Gitlab security problem

A security issue was found in our gitlab installation. However the version we have installed doesn’t look to be vulnerable (we are running the exploit ourselves and getting no results). Meanwhile we are working on upgrading our GitLab installation(s) to make it easier to follow newer GitLab releases. We are aware of the Mattermost/GitLab split, but without an alternative, we need Mattermost to keep on running. We are planning to upgrade gitlab.science.ru.nl on Thursday September 17th, this will involve some downtime for both gitlab and mattermost.

Resolved Reports

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.

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.

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.

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.

1076: Print/phpMyAdmin server problem

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

1074: U:/ home server pile problem

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

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.

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.

1072: U: / home server pile and Linux login server lilo/stitch problems

The server had a high load and stopped servicing users, probably because of problems with the creation of new snapshots at 13:00 hours. A reboot solved the problem.
