⌁ RHEL 10 filesystem · Challenge 10

Share the inode.
Preserve the data.

A critical database file must remain accessible under two names, and a stray copy is wasting disk. Create hard links to give the file multiple names, confirm they share one inode, and prove that editing one name updates the other — without duplicating the data.

Mission brief

Give the database a second name

BEGINNER

The database at /data/db/orders.db must also be reachable as /backup/orders.db. Create a hard link (not a copy), confirm both names share the same inode, and prove the link works by editing one and reading the other.

Inspect: ls -li /data/db/orders.db or stat /data/db/orders.db.

Hard link: ln /data/db/orders.db /backup/orders.db (no -s).

Verify: ls -li /data/db/orders.db /backup/orders.db — same inode, link count 2.

Prove: echo 'update' >> /data/db/orders.db then cat /backup/orders.db.
