Deep technical guides for Linux volume management, filesystems, network storage, backup, performance, and enterprise storage protocols. Each page is researched against kernel documentation, man pages, and vendor references.
Linux storage is layered: block devices sit at the bottom, partition tables and volume managers sit on top, and filesystems or network protocols sit above those. The guides below cover each layer in depth, from LVM and mdadm RAID at the block layer, through Btrfs and OpenZFS at the filesystem layer, up to NFS/SMB and iSCSI/NVMe-oF for network-attached storage.
The guides are organized into six clusters. Volume management & redundancy covers LVM and software RAID. Advanced filesystems deals with Btrfs and OpenZFS, including snapshots, compression, and self-healing. Backup & recovery walks through the 3-2-1 rule, Borg/Restic/rsync, and filesystem repair. Network storage spans NFS, SMB, iSCSI, and NVMe over Fabrics. Performance & monitoring pairs SMART disk health prediction with disk benchmarking using fio. SSD & caching covers TRIM/discard configuration and block-level caching with bcache, lvmcache, and dm-writecache. A final cluster rounds out the section with OverlayFS for containers, DM-Multipath for SAN path redundancy, and filesystem quotas.
Each guide includes command references, configuration examples, decision matrices for choosing between tools, and best-practice recommendations grounded in kernel documentation and production experience. The content targets systems administrators, SREs, and infrastructure engineers who need to make informed storage decisions on Linux.
