Linux: A Complete Practical Course

  1. 01Linux Storage Management: Disks, Partitions, LVM, Filesystems, and MountingHow Linux storage works from physical disk to mounted filesystem — block devices, partition tables, LVM for flexible volume management, filesystem creation and tuning, and NFS for network storage.
  2. 02Disk I/O Performance Analysis on LinuxUsing iostat, iotop, and fio to measure disk throughput, latency, and queue depth — and diagnosing the I/O bottlenecks that silently degrade production databases.
  3. 03Linux Namespaces and cgroups: The Foundation of ContainersHow Linux namespaces isolate processes, filesystems, networks, and users — and how cgroups enforce resource limits. The primitives that Docker, Kubernetes, and every container runtime are built on.
