drbd_md_first_sector(9)

💖 NAME 💖

Okay so this is the Kernel API Manual page for drbd_md_first_sector(9), and bestie, it does exactly one iconic thing: it returns the first sector number of the meta data area. That's it. That's the whole main-character job. ✨

🌸 SYNOPSIS 🌸

sector_t drbd_md_first_sector (struct drbd_backing_dev *bdev );

🎀 ARGUMENTS 🎀

• bdev — the meta data block device. Lowkey essential, highkey the only thing you pass in. 💅

🦋 DESCRIPTION 🦋

BTW, for internal meta data, this happens to be the maximum capacity we could agree upon with our peer node. No cap, that's the detail, and we're keeping it exactly like that. 🫶
