Today I deleted a node from 2-node cluster, followed as described in doc "Deleting a Cluster Node on Linux and UNIX Systems". After successfully deleting a node I detected that "crsctl status res -t" shows a strange thing:
I don't know is it normal that "*ora.srac.db*" shows 2 nodes? Also deleted node is alive, but without grid & rac. Maybe it's normal, because DB is functioning as rac db with 2 nodes, 2 undo, 2 redo thread and so on.
