Foreseeing problems (linux related) Sunday Jan 24 12:17:58 2021 ------------------------------ One of the things I am most proud of after using linux for 15 years that I can foresee problems before they show up. This week I had to update our HP proliant server with debian linux oldstable release squeeze and before running the magic words apt update && apt upgrad thought: Well there are two things to keep in mind here. One, one o the disks in the raid might be broken (which is often the case afte months of 24/7 service) and two, the new kernel might fail to boot. It turned out I was right. One of the disks broke and the new kerne failed to boot. Since I could not fix it remotely I had to go to th data center to manually boot the system and then remotely fix the broken kernel. The system was up and running in a few minutes thanks to my experti in dealing with broken systems. This post has nothing to do with eg or self-praise. It is just a reminder that experience is always a plus. No matter how clever or geek you are. Experience is always an extra point. I am really happy that I was able to solve the problem on a Friday and the server was up and running during the weekend ;-)
