Hi all,

When is it safe to attach a detached node? What do I need to check before attaching a node (I have one master one slave setup)?

*         Do I need to make sure replication lag is 0? If I attach a slave when replication lag is not 0 what problems can arise (if any)

*         Before I attach a node do I need to check the state of the other node?

*         What other checks to I need to do before attaching a node?
