Voyager and VuFind Problems this Afternoon (Sept 14th)

Wednesday, September 14, 2016 - 5:32pm

I apologize for the Voyager and VuFind outage this afternoon. I was doing prep work for this Sunday morning and made one change too many. The servers did not go offline but they were unable to talk across the network to the Oracle databases.

The prep work has been removed and no further changes will be made until the servers are powered down this Sunday morning.

SFX Outage (June 24, 2016)

Friday, June 24, 2016 - 9:08am

Last night (June 23) at 10:30PM I staged a firewall rule in a new security device for the Production sfx.carli.illinois.edu server. This rule was disabled but it appears that the existance of the rule blocked network access to the server. The rule was removed at 7:00AM this morning restoring service.

Throughout the rest of June and July, I will be migrating more services behind the security device and there will most likely be more interruptions to service. I will try to make sure they are short disruptions and I apologize for the outage.

Emergency Patching at 11PM Tonight (Feb 17, 2016)

Wednesday, February 17, 2016 - 3:42pm

There is a new glibc vulnerability (CVE-2015-7547) that affects most Linux systems. It may allow remote code execution on the servers, so I will patch and reboot all CARLI servers starting at 11PM tonight (Wednesday, Feb 17).

For most servers this will be a quick reboot. For Voyager, it will probably be down for about 20 minutes while the Oracle database server is rebooted.

Voyager Outage (Dec 4th, 2015)

Friday, December 4, 2015 - 9:04am

We have a batch job that has been failing this week and we have a ticket open with Ex Libris. We did not realize that the failed jobs were generating 4GB core dumps. At 2:10AM this morning the core dumps pushed the disk volume to 100% capacity. At approximately 8:50AM we identified and removed the core dump files to restore service.

This failure did not generate any automated alerts, so we will need to revise our monitoring.

Network Issues Friday (10/02) and Saturday (10/03)

Monday, October 5, 2015 - 4:41pm

The CARLI servers are in a Data Center on the University of Illinois at Urbana-Champaign (UIUC) campus. The UIUC campus firewalls automatically download the latest intrusion detection signatures and one of those signatures from the vendor was bad. At 9AM Friday the firewalls crashed and automatically restarted. A firewall restart drops all connections to our Voyager server (it probably has no effect on web traffic). At 3PM Friday, the firewalls crashed and restarted again, but now they were in a bad state that also slowed down network performance.

The poor network performance continued through Saturday evening until UIUC network staff and the firewall vendor identified the issue and removed the bad signature. Everything appears to be working normally again at this time.
