Hi All,
In Extended RAC(12.1), does the Quorum failgroup(Diskgroups with Normal Redundancy) disks need to be same size as the other disks in the respective Diskgroup?
In below example, we have Quorum failgroup for OCR diskgroup, which is 20GB(NFS) similar to other disks in its Diskgroup. So, if we want to add Quorum failgroup for rest of the diskgroups, do we need NFS disks like;
DATA: 2TB ???
FRA: 2TB ???
RECO1: 100GB ???
RECO2: 100GB ???
Please suggest appox. size of Quroum Failgroups for these 4 diskgroups. Also, is there any documentation on sizing Quorum Diskgroup
DISKGROUP DISK# FAILGROUP DISKNAME TOTAL_MB FREE_MB PATH HEADER_STATU
