C&CZ Problem Card

The server vos will receive extra disks and need to be reconfigured. Virtual clients gitlab3, redmine2 and smtp2 will be offline during maintenance.

Starting from 8:45h, the network disks will not be available during a migration to a new server. Affected disks: acfiles, aerochem, amsbackup, amscommon, beevee, bfac-backup, bio-orgchem, bioniccell, carisma, chemprac, csg-staf, csgi-archief, desda, ds, ehef1, ehef2, ehef3, geminstr2, giphouse, gissig, gmi, hfml-backup2, highres, impuls, introcie, isis, janvanhest, kaartenbak, kangoeroe, mbaudit1, microbiology, microbiology2, milkun2, milkun3, milkun5, milkun6, milkun7, milkun7rw, molbiol, mwstudiereis, neuroinf, neuroinf2, nfstest, nwibackup, olympus, puc, ruversatest, secres2, secrmolbiol, sigma, sigmacies, spectra, spm, spmdata3, spmdata4, spmdata5, spmdata6, spmdata7, spmmagstm, spmnanolab, spmstaff, ssi, staff-hfml, stroom, thalia, ucm, vsc, vsc1, vsc10, vsc11, vsc12, vsc13, vsc14, vsc15, vsc2, vsc3, vsc4, vsc5, vsc6, vsc7, vsc8, vsc9, vscadmin, wiskalg, wiskunde en wkru.

After the server reboot on Monday morning, the changes to the home directories of the last two weeks had disappeared. It is still not clear how this could have happened. The backups of Saturday June 13 22:55 have been restored.

Starting a month ago, mail programs could get an update due to the vulnerability for a LogJam attack. After this update these programs refused connections with a server with a too short key. The old C&CZ authenticated SMTP server had such a short key. Users who reported this problem (with the latest versions of Pine, Thunderbird and recently also Apple Mail), were advised to temporarily use an alternative server. As of today using this alternative server is no longer necessary, because the server smtp.science.ru.nl has been replaced by a new server.

A short power dip interrupted desktop computers and some network switches without UPS backup power on the RU campus. It took approx. 20 minutes before the affected switches became fully operational again. A network switch at the Transitorium reported a failed module until it was reset around 8:30 am on Friday morning. For ca. 46 outlets/users the network didn’t function until 8:40. The UVB reported as cause a cable cut at the Kapittelweg. Liander reports a power disturbance an hour later at that location.

Resolved by a server reboot.

The server (cn99) which serviced SUN Grid Engine on Ubuntu 10.04 is no more. It could not find its disks while booting. This will not be solved because the machine is already more than five years old. Clusternodes cn67, cn74, cn75 and cn81 are influenced. They can still be used by logging into them directly.

A configuration error caused the automatic installation of an older version of GitLab (7.7.1) over the the most recent version (7.11.4). Because the GitLab version did not correspond to the state of the underlying database, what caused multiple problems. Among which the gitlab shell for ssh access and inaccessibility of some parts of the web interface. The problems were solved after upgrading to version 7.11.4.

Today the license server booted without configuring the network. The cause of the problem was an error in a configuration file. This has been corrected. Affected licenses: Altera Ansys Accelrys Genesys Hdlworks Idapro Xilinx IntelCompiler Ingr Maple Mathematica Matlab MentorGraphics Mestrelab Topspin Orcad Originlab

The IMAP server will be replaced by a new server next Monday night. During the night, no Science mail can be read from the server, because then the most recent mails will be synchronized to the new server. Mail can be sent in this period, but new mail will start being delivered on the new server from 07:30. A word of warning, one could login on the old server with the first 8 characters of the password, the new server only accepts the full password.
