Rescue a Linux Server That Collapsed With 5 Easy Steps

Linux and Lego. They don’t just begin with the same alphabet. They have the same destiny. And they fuel the same paradox. While every builder, every child, every thinker, every artist is different – they all use Lego blocks to create what’s in their minds. Linux, too, has become as pervasive, versatile, and mainstream as these Lego blocks. And it is helping in the creation of a new world of IT for many developers and enterprises.

At the last count, as many as 85 percent of all smartphones were running on Linux using the Android operating system. Moreover, with 100 percent of the world’s top 500 supercomputers that run on Linux and with 96 percent of the world’s top 1 million servers that run on Linux, there is not much doubt why Linux is considered so flexible yet so robust and reliable. Even 90 percent of all cloud infrastructure operates on Linux.

Linux development – great, but full of question-marks

Yes, the Linux Foundation’s Annual Report 2021 adds that over 5.4 billion people rely on Linux as it powers the vast majority of smartphones, the world’s largest cloud environments, and the world’s fastest computers. But it also highlights the dangers Linux is exposed to. The project has been shipping new code, features, and performance enhancements in three decades of Linux development. Still, it is also cognizant of cybersecurity threats and the fragility of software supply chains that are constantly under attack by an increasingly sophisticated adversary. The foundation underlined how in 2021, there was a lot of progress in its quest to ‘harden’ the software supply chain.

Ditto- as seen in TrendMicro’s 2021 Linux Security report, highlighted the cost of the applications and workloads exposed to the internet-run web applications. Web application attacks emerged as the most common attack vector in its telemetry. As to the attacks on Linux systems, 76 percent of the attacks were web-based, and 24 percent of the attacks were non-web in nature. According to a report by Snyk, misconfiguration was the second top incident type in cloud-native environments. About 56 percent of survey respondents experienced a misconfiguration or known unpatched vulnerability incident involving their cloud-native applications.

In short, it is very, very crucial to keep Linux development and Linux support safe and well-oiled. The entire gamut of Linux development and Linux support should make sure that Linux applications and servers are safeguarded well. That means an enterprise should have the essential toolkit to leverage whenever there is a blip on the Linux radar.

Linux support – master these simple tricks

So can you rescue a Linux server that collapsed? Can you figure your way out when a Linux server becomes unresponsive? If not, here is a small guide to picking up the Lego blocks, one by one:

  • Check the hardware- cables, devices, ports, and racks. Check if there are any faults in memory aspects with special memory kernels or programs for memory tests.

  • Find the top command, average load on the server, the resource usage – find the processes that hog most of the IT fuel.

  • See if you have run out of disk space. Check log files and scan and then -Initiate rescue mode, log into the system with a special-purpose control panel or a VNC if you have a VNC client installed.

  • Boot the server, identify your disk partitions before recovering, run a test on the disk, scan disk failures and recover or back-up data if disk issues exist.

  • Correct the exact source of errors – unmount the disk, reboot the server from the panel, and end rescue mode. Alternatively, you can use DevOps tools to create a new server and repair the old one.

A company that is adept in Linux consulting and Linux support would be the perfect friend to guide you in getting ‘up and running as soon as possible. However, do not make the mistake of letting it run below the radar. It is inefficient and highly-inadvisable in the current threat landscape that haunts even the most minor crack in Linux development.

Keep building whatever you want with your Lego called Linux. Just make sure that you do not let the pieces fall into the wrong hands. For more information, talk to our experts today.
