I followed the SMB /CIS and NFS Multiprotocol Configuration guide for ontap 9.7
I was able to create the SVM, volume etc as the guide describes.
I am able to go to a Windows servers and successfully access the share and write to the volume.
When I log into my Red Hat Linux 7.9 client I am able to sudo bash and do mkdir /mnt/folder
When I enter the command "mount -t nfs -o nfsvers=3,hard <data lif IP>:/test (volume name) /mnt/folder
I get the error mount:nfs access denied by server while running mount <SVM IP>:/test
My export is set to include the IP of the server I am trying to mount the volume test on with access protocols CIFS/NFS read-only rule never, RW rule Any, Superuser access Any. I applied this export to to volume in the junction path.
Under Host users and name mapping I set Unix to Windows pattern (.+) replacement ENG\\1 and under Windows to Unix the pattern is ENG\\(.+) and replacement is \1. This what is recommended to do in this manual.
I am no Unix guru but I have ssuccessfully set up NFS SVM's and have been able to mkdir /mnt touch files on this same Unix server.
Not sure where I went wrong or what other information would be helpful to troubleshoot this? THanks.
