C&CZ Problem Card

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

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.

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.

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.

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.

One of the systemdisks reported SMART-errors and will be replaced.

Lilo did not shut down correctly during the planned weekly reboot. After a hardware reset, the machine booted just fine

Just like yesterday, a reboot of the machine was necessary to restore the functionality. Tomorrow morning, the server will restart with a new kernel. It this doesn’t solve the problem, we will look into a new version of Samba.

Just like yesterday, a reboot of the machine was necessary to restore the functionality. We will investigate if we can remediate this problem with newer software versions (Samba, Ubuntu, …)
