1) Can't comment, but worked on a customer which was a NetApp shop. Went
with the recommendations they provided in several of their whitepapers etc.
Go with Oracle direct NFS anway
2) ...
3) That was a temporary thing - support re-introduced in 19c, and you
should go to 19c anyway for support reasons
4) Yes. Same customer (NetApp 'stretch' cluster running RAC). Ran well, but
judicious use of services to control application workload partitioning

Hello Oracle DBAs,
We have some problems with DM multipath ( mixed SCSI and ISCSI devices) =>
oracle instance can fall.
So we plan to use NFS for the quorum disks.
I have some questions :
1) many people use hard options for NFS, but oracle recommended soft
options => not a big fan of hard option, why people not follow it ?
2) oracle recommend now one quorum disk for each diskgroup for steched
cluster, but i did not see people use it
3) 18C => oracle do not support NFS for Voting and OCR , What does it mean
?
4) Does someone try to use exetend cluster configuration with RAC in
production ?
If people have recommendations about NFS usage with Rac extended clusters,
i will appreciate.
Thank you
