Description
sql.mit.edu is a separate IP that is bound by the server that is the primary at the time. LVS provides a similar service for the Scripts primary, and would be convenient and consistent to do so for SQL.
However, this would require doing something clever as the directors are not on the backend network.
Note: See
TracTickets for help on using
tickets.
Mitch sayeth: "This is more complicated than Scripts, because to switch SQL, we want to stop accepting connections on the outgoing holder of the shared IP, wait for running queries to finish, and wait for replication to catch up on the incoming shared IP holder before accepting connections there. LVS doesn't offer that without more magic. "
