Do not delete/reconfigure a node when the node is in Unpinned status
[root@grac42 ~]# olsnodes -s -t
grac41 Inactive Pinned
grac42 Active Unpinned
grac43 Active Unpinned
Trying to recover by running crsctl delete node
[root@grac43 app]# crsctl delete node -n grac41
CRS-4661: Node grac41 successfully deleted.
[root@grac43 app]# olsnodes -s -t
grac41 Inactive Pinned
grac42 Active Unpinned
grac43 Active Unpinned
--> You can only UNPIN the Node if the CRS stack is up and running on that node
Summary
- Node is still pinned and can’t be added to the cluster anymore
- Even Delete Node doesn’t cleanup the Inactive and Pinned Node grac41
- The only solution is to recreate the OCR from scratch
