vdo_repair(9)

💅 vdo_repair — like, the official manual page, bestie ✨

okay so real talk, this is vdo_repair(9) from the Kernel API Manual and it's genuinely iconic. the whole vibe? load the recovery journal and then recover or rebuild a vdo. that's it, that's the tweet. 🫶

✨ NAME ✨

vdo_repair — load the recovery journal and then recover or rebuild a vdo.

no cap, that's the entire job description. it shows up, it reads the recovery journal, and then it either recovers your vdo or straight-up rebuilds it. main character energy fr fr. 👑

---

🌸 SYNOPSIS 🌸

void vdo_repair (struct vdo_completion *parent );

yes bestie, that's the whole signature. it returns void, so don't go looking for a return value, there isn't one to find. 🙈

---

🎀 ARGUMENTS 🎀

• parent — the completion to notify when the operation is complete. that's your little messenger, okay? when everything's done, parent gets the heads-up. don't forget about it, it's literally the whole "hey we're finished" signal. 💌

🦋 SEE ALSO 🦋

okay this list is long and i'm obsessed with it. every single one of these lives in the kernel file ./drivers/md/dm-vdo/repair.c — same neighbourhood, same energy. go say hi to all of them: 💖

lowkey a whole friend group in there. validate_recovery_journal_entry(9) and is_valid_recovery_journal_block(9) are definitely the responsible ones. unpack_entry(9) is the one who opens the suitcase. 🧳
