Oracle RAC 19c not starting on one out of two nodes after server restart having Oracle Linux 7.6
1. We have 2 node Oracle RAC 19c (19.3.0.0) database installed over Oracle Linux 7.6 x86-64 (UEK). We gracefully shutdown cluster on each node and restart it turn by turn. The secondary node started normally after server restart and joined cluster services. However, primary node after restart is not joining cluster and is giving following errors when starting CRS:
PROCL-26: Error while accessing the physical storage Operating System error [No such file or directory] [2]
CRS-4000: Command Start failed or completed with errors.
2. Upon running ocrcheck on this node, following output is observed:
PROT-602: Failed to retrieve data from the cluster registery
PROC-26: Error while accessing the physical storage Storage layer error [Insufficient quorum to open OCR devices] [0]
