The evolution of storage on Linux
summary
A concise checklist: Linux accumulates 40+ filesystems in the kernel; early limits like Minix 64 MB and EXT1’s 2 GB give way to EXT2/3/4, XFS and JFS that push to terabytes; journaling via jbd/journaling turns multi‑hour fsck into minutes; logical volume flexibility comes from device-mapper and LVM2 with thin provisioning; dm‑cache uses a flash device as a working cache and actually speeds real workloads; cluster solutions (OCFS2, GFS), DRBD replication and ZFS/Btrfs provide distributed, fault‑tolerant storage.
