I previously encountered this issue on my 10.2 RAC nodes running on top of HP-UX. I faced it the 2nd time when performing postclone operation on a Oracle EBS 12.0.0.5 on AIX. This time, the error popped up when I’m trying to perform postclone for Oracle EBS HCM module on a RHEL 4U6 x86-64. A reference in using nfs for Oracle can be found here. My NFS partition is mounted using :
mount 172.16.2.82:/hcmdev /u01 -o rw,bg,intr,hard, timeo=600,wsize=32768,rsize=32768,vers=3,tcp
I don’t have to put “noac” on the option since the RHEL node is not an RAC cluster
