description
Diagnose and fix Linux disk full / no space issues. Find large files, clean logs, purge package caches, remove old kernels, handle Docker disk bloat, and expand filesystems. Use when df -h shows space critically low, applications fail with "no space left on device", or docker builds fail with ENOSPC.

Free disk space fast.

Quick Assessment

df -h
du -sh /* 2>/dev/null | sort -rh | head -20

# Journal logs
journalctl --vacuum-time=7d

# Docker
