USAGE
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.
ARCHITECTURE
Processes
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.
