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.
