NAME
mogilefsd — MogileFS tracker daemon
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.
Checker/Fsck— background filesystem consistency checker- See MogileFS::Worker::Checker.
Data Storage
See MogileFS::Store.
