The fileserver crashed. After a reboot everything was back to normal.
The fileserver failed to reboot during the regular Monday morning shutdown schedule. It was possible to gain access to the system console only after having removed all power from the chassis. Snapshots were removed using the rescue reboot but rebooting the machine resulted in a faulty filesystem. We were able to boot the system after all filesystems had been checked offline. These actions resulted in a unusual long downtime.
Problem: Crash due to defective disk Solution: Deactivated disk using hot spare and reboot
The fileserver failed the regular Monday morning reboot. Only after a rescue boot and a manual removal of all snapshots rebooting the machine worked.
Problem: Stack: Crash due to failing disk. Solution: Deactivated disk using hot spare
Pile did not shutdown properly during weekly reboot due to a kernel panic. Solution: Executed power-cycle of the system
Again a Science user supplied his Science password to phishers. We notice that because Internet criminals use these passwords to get into the Science mail servers (horde webmail, smtp) in order to send spam. PLEASE: do not naively click on a link in an e-mail!
Was waiting for interactive input after reporting a warning (^d)
While performing maintenance (removing a network card) a network cable was not inserted correctly.
Yesterday Matlab R2013a has been installed. Today at 13:00 hours many servers started to automatically copy this 5.4 GB to their local disc. Some parts of the network were overloaded by all these copying, which made accessing the network slow for many users. The distribution of this software will now be scheduled to happen over a longer period, primarily outside of working hours.
