MogileFS tracker daemon


This is the main MogileFS daemon, mogilefsd, also called the "tracker".  All interaction with a MogileFS installation begins by a client talking to a tracker (you should run several in parallel for redundancy).

See MogileFS::Client for a client library.



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 bunch of worker processes underneath.

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.
