CPK messages are initially sent to the CPK mailing list, you can (un)subscribe via this link. You can also follow the service interruption messages via RSS using the link in the title under the RSS icon. If the CPK takes more time to resolve, any updates are published on this website.
Even though we closed CPK #1359, the user’s shares are not all restored. We have recovered the data from cephfs to temporary storage that is not accessible to users, it will take a bit more time to find new permanent locations for this data. The storage will not be cluster based anymore, but single server ZFS with snapshots.
Some users were unable to login, the server had become unstable, which made a reboot necessary. Unfortunately, the jupyterhub service still needs a manual startup, which didn’t happen until 13:24 hours. The service is now working again. We are working to fix the reboot problem.
A typo that could propagate to shutdown the DHCP server had the effect that some network devices did not get an IP address when they were switched on and that others, whose address lease expired in this period, lost their IP address and thus their access to the network.. We’ll improve the process to prevent a typo from bringing down the DHCP server in the future.
After a scheduled reboot of the machine running jupyterhub, jupyter failed to start properly. The service started after invoking a manual start command. The measures taken to resolve this recurring problem have not proven to be sufficient.
Due to a misconfiguration of the DNS in the z.science.ru.nl zone, all shares were not available during the outage. Extra tests are added to prevent a future occurrence.
The router for most Science services urgently needs a reboot. This has been scheduled for early morning. In the unlikely case that this reboot fails, ILS Connectivity is on campus to fix it.
In preparation of the migration to Microsoft Exchange Online Protection (MS EOP), we added another mail exchange server (mx5) to be addressed directly by MS EOP. However, having had mx4 in production for some time, we forgot to test mx5 in conjunction with our mailman server (zaaivm). This could result in a bounced mail ’not accepting messages’ for FNWI users (employees and students) using @ru.nl addresses. Meanwhile, mx5 has been made known to zaaivm thus resolving this issue....

After an upgrade of Roundcube it was temporarily not possible to send e-mails. After a small change in the configuration file the problem was resolved.
The poster printer kamerbreed was broken. It couldn’t be fixed, so we ordered a new HP Designjet Z6 44 inch postscript. The ordering and delivery took way too long, the new poster printer was in operation on November 13. The new printer is twice as fast, so the speed of service will be even better. When our poster printer breaks down, users that need posters can go to Radboud Post&Print.
For an unknown reason, the Jupiter and Chemotion servers didn’t start. We are currently looking at how we can start the machine again. The virtual machines have been rebuild, based on their existing disks.
