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#1100 M1.04 no network

While administering the network switchports for the move of ISIS to Mercator1 floor 0 to 3, ISC network management erroneously also changed the configuration of the network switchports of floor 4. When this was reported this morning, it could be readily remedied.

One of the mirrored disks failed. We didn’t manage to rebuild the raid set with a new disk. The system is reinstalled with two new disks. After that, data from /scratch could be recovered from one of the old disks.

The network drives will be migrated to a new server. During the migration, the network drives will be unavailable. Affected shares: acfiles, bioniccell, bio-orgchem, celbio1, CSGI-Archief, Csg-Staf, ds, evsf2schijf1, giphouse, gissig, gmi, hfml-backup, hfml-backup2, highres, impuls, introcie, isis, kaartenbak, microbiology, microbiology2, microbiologyftp, milkun2, milkun3, milkun5, milkun6, milkun7, milkun7rw, mwstudiereis, neuroinf, olympus, permissies, puc, secres2, sigma, sigmaalmanak, sigmacies, sigmaexchange, sigmasymposium, Soheto, splex, spmdata3, spmdata4, spmdata5, spmdata6, spmdata7, stroom, thalia, ucm, vsc, vsc1, vsc2, vsc3, vsc4, vsc5, vsc6, vsc7, vsc8, vsc9, vsc10, vsc11, vsc12, vsc13, vsc14, vsc15,wiskalg, wiskunde

CPK#1098 Reboot of login servers after network drive migration

The planned move of network drives from an old to a new server caused a lot of “stale NFS file handles”, which made it necessary to reboot some login servers.

CPK#1096 IMAP mail server problem

The IMAP server got overloaded again. Restarting the IMAP service was required to bring it back in operation. We think it is related to snapshots and therefore regularly remove invalid snapshots from now on.

CPK#1095 IMAP mail server problem

The IMAP server got overloaded. Restarting the IMAP service was required to bring it back in operation.

CPK#1094 Data/file/vol server (heap) problem

The server had a problem, which had started at the Monday morning reboot. A reboot of the machine solved the problem. Soon all data will be moved to a new server. This will not cause much problems for users, because everybody uses the aliases something-srv.science.ru.nl.

CPK#1092 Maintenance wireless infrastructure May 19

At Monday May 19, a major upgrade of the wireless infrastructure and its maintenance tool (called Prime) will take place by the ISC. Therefore the wireless service (i.e. Eduroam) will be interrupted several times from 8:00 pm. Existing wireless connections will be lost and new connections will not be possible for some time. Due to the complexity of this operation this maintenance will possibly be continued at Monday, May 26, again with interruptions from 8:00 pm.
