EBS 12.2.3 database 12.1.0.2 RAC 2 nodes, upgrading to 19.10
We are upgrading our 12.1.0.2 2 node RAC database to 19.10.
Currently the datafiles are on ocfs2 and the ocr is on nfs as well as the $ORACLE_HOME and a few other file directories.
We are upgrading the 12.1.0.2 database to 19.10
The new file system will be all NFS.
I found this note: Mount Options for Oracle files for RAC databases and Clusterware when used with NFS on NAS devices (Doc ID 359515.1)
it say's Mount options for CRS Voting Disk and OCR (12.1 and lower)
In 12.2, both OCR and voting disks must reside in ASM.
Refer to Document 2201844.1
The NFS storage for asm diskgroup (not quorum disks) that has the OCR and voting disk must also use this mount options
