One of the Secondary node delay seriously，so remove the node, stop instance and rm data, at last restart instance for sync data automatic.
Sync data, time to begin 2018.1.25 11:00:00, and end 2018.1.29 14:38:00.It lasts 4 days. And each node data is 2.5T.
But at 2018-01-29 14:26, it suddenly occured error. The deail message is:
