C&CZ Problem Card

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.

Ceph filesystem storage is experiencing reduced performance, because one of the storage nodes is currently offline. A combination of factors causes this to affect performance, fullness, uneven distribution of data over the storage nodes. We expect this to be resolved when the node is back in the cluster. update 7 Oct 2023 The cluster is mostly complete again for a while already, but there’s a lot of remaining issues to be resolved by the cluster. Performance may or may not be affected…

The RU contract with the anti-SPAM/anti-phishing service Proofpoint expired September 21, 2023, which means that ‘Proofpoint End User Digest’ mails are not sent anymore after that date. C&CZ is migrating Science mailboxes to the anti-SPAM/anti-phishing service of Microsoft Exchange Online Protection. There is an increased chance of receiving SPAM/phishing mails in the Science mailbox during this migration period. P.S. the RU central mailboxes (with addresses ending in @ru.nl) have already been migrated to Microsoft Exchange Online Protection. ...

The Science newsletter is sent from an @ru.nl mail-account. Recently, the @ru.nl mailservice was changed by adding Exchange Online Protection (EOP). EOP is the successor for Radboud University to the Proofpoint e-mail security filter. EOP added a mail header line to the newsletter List-Unsubscribe: https://c8ce19ec62454d21b73b7d5a25559d8f.svc.dynamics.com/t/lu/7... which made the mail appear to be spam to the Science spamfilter SpamAssassin. 1.1 URI_HEX URI: URI hostname has long hexadecimal sequence When we noticed this, we fixed it by welcome listing (allowlisting/passlisting) the sender address communications-science@ru.nl on September 7, so this mail will never be falsely classified as spam. The Radboud Weekly newsletter had the same problem, so communicatie@ru.nl was also put on the welcome list on September 14.

After the Monday morning reboot, the NFS server on home1 refused to start properly. We are investigating why a manual restart of nfs was needed.

RU mail management let us know that yesterday the forwarding to external (non-RU) mail addresses has been stopped as announced earlier. Unfortunately, mail for several dozens of Science users was/is not forwarded to the Science mailservers. These mails can still be found in MS365 (RU mail), either in the Inbox or in the Deleted Items. RU mail management promised that the forwarding will be corrected tomorrow.

Announcement of maintenance, Wednesday afternoon we are going to replace the cpu of one of our main vmhost servers, meaning vms gitlab9 (pep) slurm22 pep3 jitsivm poliep indicoimapp2vm pep4 mariavm01 smtp2 will be down for up to 1 hour. several services depend on the mariavm01 (websites, slurm), so they will be affected too.

Our daily backup system relies on cephfs storage, which is currently offline, see CPK#1337. This means that as of July 22nd we are unable to perform or restore daily backups. When the cephfs problems are resolved the daily backups should also be OK and restorable again. NB, this has no effect on the Monthly backups, which continue to work normally.
