Tmpfs vs ramfs on Linux: mount RAM-backed filesystems for blazing-fast temp storage. Covers fstab, Docker tmpfs mounts, CI/CD use cases, and the key differences.

You updated a container and the database is gone. The bind mount and permission mistakes that lose data, named volumes as the fix, and how to check.

MinIO vs SeaweedFS compared for self-hosted S3 storage: setup, performance, Docker Compose configs, S3 API compatibility, and which one fits your home lab or production workload.

Replace Nextcloud's local filesystem with MinIO as an S3-compatible backend. Full Docker setup, bucket policies, performance tuning, and why this scales better.

Master LVM snapshots and thin provisioning on Linux. Learn to create, use, and merge snapshots for backups, and over-provision storage safely.

Docker volumes vs bind mounts explained: named volumes, anonymous volumes, bind mounts, and tmpfs. Real examples for databases, dev workflows, and production.

Default mount options and journald settings burn SSD write endurance. Check health with smartctl, mount noatime, move logs to tmpfs, find the real writer.

docker system prune reclaims space and can delete volumes you wanted. What each cleanup command removes, how to check usage first, and a safe script.

Compare zram (compressed RAM) and traditional swap files. Learn when each works, setup, and real-world performance trade-offs for memory-constrained systems.

What is lost+found and why does it exist? fsck puts recovered file fragments there after a crash, and no, you can't delete it.

The -v and --mount flags for Docker volumes explained, bind mounts vs named volumes, read-only, propagation, and tmpfs options.

LVM lets you resize volumes, add disks, and take snapshots without repartitioning, PVs, VGs, and LVs explained with real commands.
