MOGILEFSD(1)

✨ MOGILEFSD(1) ✨

okay bestie, gather round 💖 this is the man page for mogilefsd, and yes it's a Perl thing — User Contributed Perl Documentation, living in section 1 of your friendly neighborhood manual. Let's get into it 🦋

---

🌸 NAME 🌸

mogilefsd — the MogileFS tracker daemon. that's it, that's the name, she's simple and she's iconic 💅

---

🌈 USAGE 🌈

So this right here? This is the main MogileFS daemon, mogilefsd, and everybody calls her "the tracker". She's the moment. ✨

The way it works: every single interaction with a MogileFS installation starts with a client talking to a tracker. That's the whole vibe. No tracker, no talky-talky.

🫶 Pro tip straight from the source: you should run several trackers in parallel for redundancy. Not one. Several. Redundancy is self-care, bestie.

Also, if you're the client-y type and you want a library to do the talking for you, go look at MogileFS::Client. 😌

🧚 ARCHITECTURE 🧚

👑 Processes

Okay so here's the tea: the mogilefsd daemon is an event-loop in the parent process, handling — with epoll/kqueue/etc (see Danga::Socket) — tons of client connections, while managing a whole little squad of worker processes underneath. Main character parent process, hardworking little worker bees. it's giving delegation, fr fr 🐝

The worker processes under mogilefsd include:

• Client query processing — implements the MogileFS client/server protocol. ✨ See MogileFS::Worker::Query.
• Monitoring — monitors hosts and devices. 👀 See MogileFS::Worker::Monitor.
• Replicate — replicates files. 📁 See MogileFS::Worker::Replicate.
• Deleter — deletes files from storage nodes (protocol deletes from namespace are immediate). 💀 See MogileFS::Worker::Delete.
• Reaper — re-enqueues files for replication when disks are marked dead. 🌾 See MogileFS::Worker::Reaper.
• Fsck — background filesystem consistency checker. 🔍 See MogileFS::Worker::Fsck.

🍓 Data Storage

See MogileFS::Store. (yes that's all, she's mysterious, she's lowkey shy) 🙈
