Add the push process description

Line 64: Line 64:

* Changes can be staged (sync data first, repodata second)

* Less out of sync mirrors for yum

=====How push works=====

Below is a short description of the push process:

# Master mirror updates timestamp file

# Master initiates ssh into tier 1 mirrors to start stage 1 sync (wait)

# Tier 1 mirrors rsync everything but repodata from designated targets (no delete)

# Tier 1 mirrors initiate ssh into tier 2 mirrors to start stage 1 sync (wait)

# Repeat prior to steps for each tier under 2

# Master initiates ssh into tier 1 mirrors to start stage 2 sync

# Tier 1 mirrors rsync everything from designated targets (with delete)

# Tier 1 mirrors initiate ssh into tier 2 mirrors to start state 2 sync

# Repeat prior to steps for each tier under 2

# Master mirror checks freshness of mirrors and generates mirrorlists
