Learn Linux Filesystem - Pre-Requisite Skills & Environment Setup
Before touching any filesystem, you need to master the Linux CLI, partition management, mounting and /etc/fstab, and the block device concept. In this episode you set up a VM/lab experiment and install the e2fsprogs, xfsprogs, btrfs-progs, and OpenZFS toolchains.

Learn Linux Filesystem - History, Background & Why You Need It
The Linux filesystem evolved from the simple ext2 into the feature-rich ext4, XFS, btrfs, and ZFS. This episode traces the history of each filesystem, the storage problems they solved, and why understanding filesystems is crucial for server operations.

Learn Linux Filesystem - Core Concepts & Anatomy
Every filesystem is built from the same building blocks: inode, superblock, and block allocation mechanisms. This episode dissects the on-disk filesystem anatomy, the difference between journaling and Copy-on-Write, checksum self-healing, and how VFS unifies everything.

Learn Linux Filesystem - ext4: Concepts, Tools & Daily Operations
ext4 is the most widely used default filesystem in the world. This episode covers the concepts of data=ordered journaling, extents, flexible block groups, and delayed allocation, then hands-on practice with mkfs.ext4, tune2fs, dumpe2fs, e2fsck, and resize2fs.

Learn Linux Filesystem - XFS: Design, Tools & Operations
XFS is the RHEL/Rocky default filesystem designed for high throughput and large capacity. This episode covers allocation groups, B+trees, and XFS journaling, then hands-on practice with mkfs.xfs, xfs_info, xfs_growfs, xfs_repair, and xfsdump/xfsrestore.

Learn Linux Filesystem - btrfs: Subvolumes, Snapshots & COW
btrfs brings Copy-on-Write, checksums, subvolumes, and snapshots to the Linux kernel. This episode covers btrfs COW and checksum concepts, then hands-on practice with btrfs subvolume, snapshot, send/receive, balance, device management, check, and scrub.

Learn Linux Filesystem - ZFS: Pools, Datasets & Snapshots
ZFS combines a filesystem and volume manager in one entity with checksums and self-healing. This episode covers pools and vdevs, filesystem datasets and zvols, snapshots and clones, send/receive, and scrub to guarantee data integrity.

Learn Linux Filesystem - Mount, fstab & Options
Every filesystem that's been created must be attached to the directory tree via mount. This episode covers mount and /etc/fstab, UUID as a stable reference, per-filesystem mount options, then systemd-mount, automount, and mount/swap units for modern management.

Learn Linux Filesystem - Quota, Encryption & Integrity
Production filesystems need limits, confidentiality, and verification. This episode covers user/project quotas on ext4 and XFS plus btrfs qgroups, encryption with LUKS and ZFS native encryption, and scheduling checksum scrubs to detect silent corruption.

Learn Linux Filesystem - Snapshots, Backup & Replication
A snapshot is a quick photograph of a filesystem's state, and replication spreads it elsewhere. This episode covers snapshots for ext4/XFS via LVM and fs-freeze, instant btrfs and ZFS snapshots, then incremental btrfs send/receive and zfs send/receive patterns for offsite backup.
