LEIL-HDD.CFG(5)

📦 version 5.12.0, in nixpkgs unstable

🌸 NAME 🌸

okay bestie, welcome to the LEIL-HDD.CFG(5) manual page 💖. This one is all about leil-hdd.cfg — the list of LeilFS storage directories for leil-chunkserver. It's giving "guest list but for your storage era." Periodt.

✨ DESCRIPTION ✨

The file leil-hdd.cfg contains list of directories (mountpoints) used for LeilFS storage (one per line). No cap.

A directory prefixed by the /* character causes given directory to be freed by replicating all data already stored there to another locations. Lines starting with the # character are ignored. Lowkey important, highkey iconic.

The chunks are divided into metadata (.met) and data (.dat) parts. The metadata parts contain information about the chunks, while data parts are only aligned data. The way that metadata and data get their own little lanes? Obsessed. It is possible to store the metadata parts in a different directory, or even in a separate drive, by splitting both paths using ' | ':

/path/to/metadata | /path/to/data

This way, the metadata parts can be stored, for instance, in NVMe and the data parts in HDD. Split-path era fr fr.

🔥 HOST-MANAGED SMR SPECIFICS 🔥

With the proprietary chunkserver plugin for Host-Managed SMR drives, use the zonefs: prefix with the following syntax:

[*]zonefs:/path/to/metadata | /path/to/data

For example:

zonefs:/mnt/nvme1 | /mnt/host-managed-smr1
⚠️ vibe check: note that the /path/to/metadata should always be on a non-SMR drive. The optional * has the same meaning as described above and marks the drive for removal. iykyk — slay the setup, but respect the SMR rules 💅.
