Service Interruptions


1407: NFS problems under investigation

When we moved the gateways of our networks from the old location to the new firewalls, we have received some complaints about NFS filesystems having slowness, longer delays or unavailability. In general NFS should never be a requirement for a clusternode job if you can avoid it, because this I/O is always much slower than local I/O from /scratch. We are investigating how we can optimise the network to resolve this issue, but we are hard pressed to know the exact cause of the problem....

1350: Mailman not accepting messages

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....

1349: Jupyterhub22 refused to start this morning

After a scheduled reboot of the machine running jupyterhub, jupyter failed to start properly. The service started after invoking a manual start command.

1348: Roundcube problem

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.

1347: Poster printer kamerbreed broken

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.

1346: Jupyter and Chemotion offline

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.

1345: Ceph performance degraded due to broken storage node

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....

1344: Increased chance of SPAM/phishing mails in Science mailbox

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....

1343: Science and Radboud Newsletter in Spam

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....

1342: Some home directories not available

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.

1341: Missed RU mail due to stopped external forwarding

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.
