Tune an ext4 Filesystem Script

Storage & Disk · medium · solved in-browser (no VM needed) · 3 tiered hints

Write /home/player/tune.sh: a bash script that retunes the ext4 filesystem on /dev/sdb1 with tune2fs. Set the reserved-blocks percentage to 1 (-m 1), set the maximum mount count to 30 (-c 30), and add the dir_index feature (-O dir_index). Start with a bash shebang and set -euo pipefail. (Authored config, graded structurally — the engine isn't run here.)
