Date | Planned | Outcome |
---|---|---|
2024-05-18 | Significant code update. | Lots of minor code changes (that add up to a pretty big change) in preparation for switching compilers. (All code must compile cleanly.) Everything passed regression testing, so it's time to push it to production. There should be no downtime. Work completed: zero downtime |
2024-04-20 | Kernel updates and patching. | Kernel patch installed! Previous stress test failed to trigger the crash. (Crossing fingers) This looks like it might resolve the problem. Downtime: about 6 minutes. |
2024-04-09 | Hard crash and reboot late at night. | I tracked down the bug! It's a kernel bug. Reported it and am looking for a workaround. Total downtime: about 1 hour, but worked on the server from 2am to 5am as I tried to debug the problem. |
2024-03-24 | Hard crash and reboot. | Yesterday's update generated problems last night. Required rebooting the server. Then the FotoForensics instance reported a drive problem and required a manual fsck. Everything seems happy now. Downtime: 7 minutes. |
2024-03-23 | Server patching and reboot. | Typical update; reboot took less than 30 seconds. |
2024-01-20 | UPS battery extender. | Test took longer than expected but was successful. (Had to buy a crimper, ring terminals, and shrink tubing to rig it up.) Good news: Battery extender has been installed. Previously I had about 54 minutes of emergency power. Now I have over 4 hours. (If the power is out longer than 4 hours, then the ISP will go down before me.) Total downtime for this installation: 20 minutes -- 10 minutes while removing the UPS and (a few hours later) 10 minutes while reinstalling the UPS. |
2023-12-30 | Installing a UPS battery extender. | Could not install. Device arrived damaged from Amazon. Good news: getting a refund. Bad news: no battery extender. I still have about 1 hour of battery. |
2023-12-23 | Server patching and reboot. | Debugging a possible kernel issue. Debug was performed on the backup server; no downtime on this server. |
2023-12-16 | Server patching and reboot. | This was a typical update. Zero downtime. |
2023-11-18 | Debug and correct the UPS monitoring. | Found the problem. The UPS monitoring software ('nut') decided that it was always supposed to shutdown the UPS. Disabled by editing /etc/nut/upsmon.conf and removing the line "POWERDOWNFLAG /etc/killpower". Now every UPS is being monitored properly. (Downtime: about 4 minutes.) |
2023-11-11 | Server patching and reboot. | During the reboot, the UPS monitor went crazy and decided to automatically turn off the UPS. We were not able to debug the problem within the maintenance window. As a temporarily workaround, we've moved the UPS monitoring to a secondary system. |
