In this lesson
Prepare for the Linux+ XK0-006 exam (CompTIA Linux+ V8). In this lesson: power and boot failures, kernel panics and GRUB fixes, full, read-only, and unmountable filesystems, data corruption and failing devices, killed processes and memory leaks, and configuration problems like PATH, failed units, and missing drivers, with Pinecrest Media, a fictional video streaming company, as the running example. Includes three original practice questions.
Preview the topics
- After a kernel update, enc07 stops at boot with a kernel panic: it cannot mount the root filesystem. The previous kernel boots fine. What is the most likely fix?
- A storage server reports No space left on device, but df -h shows 40% free on /srv/thumbs. What should the admin check next?
- lspci lists a new network card, but no interface appears. lspci -k shows a kernel module, but no driver in use, and a file in /etc/modprobe.d names that module. What should the admin do?
