Roy, It came down to manually mounting ovirt-storage domains and executing chown command. Still, I took you advice and did NFS3-only and NFS4-only tests. Here are the results: Test1: Protocol NFS3 / ExportPolicy NFS3 with Default (allow all) * ERROR: [ INFO ] TASK [ovirt.hosted_engine_setup : Add NFS storage domain] [ ERROR ] Error: Fault reason is "Operation Failed". Fault detail is "[General Exception]". HTTP response code is 400. [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Fault reason is \"Operation Failed\". Fault detail is \"[General Exception]\". HTTP response code is 400."} * Volume is mounted as: 172.17.28.5:/ovirt_hosted_engine on /rhev/data-center/mnt/172.17.28.5:_ovirt__hosted__engine type nfs (rw,relatime,vers=3,rsize=65536,wsize=655 36,namlen=255,soft,nolock,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=172.17.28.5,mountvers=3,mountport=635,mountproto=udp,loc al_lock=all,addr=172.17.28.5) * ls -la /rhev/data-center/mnt: [root@ovirt-hv-01 mnt]# ls -la total 4 drwxr-xr-x. 3 vdsm kvm 48 May 31 07:55 . drwxr-xr-x. 3 vdsm kvm 17 May 31 07:50 .. drwxrwxr-x. 2 root root 4096 May 29 10:12 172.17.28.5:_ovirt__hosted__engine * change ownership of mounted volume to vdsm:kvm * umount Reran deployment script and deployment completed successfully. Test2: Protocol NFS4 / ExportPolicy NFS with Default (allow all) Deployment went through without single issue. Seems that even though vddm:vm group with an ID 36 are created and added to NetApp volume, they are not applicable. It still required to mount manually, execute “chown -R vdsm:kvm <mounted_location>”, amount and rerun the deployment script or rather reenter storage information for deployment to proceed. Adding next storage domain, fro example for all other test VMs, will again fail from UI, unless the manual mount and chow are executed previously. Then I tried just mount second storage domain, and it failed reporting permission issue (which it was). After executing manual mount actions, adding domain from UI worked flawlessly. Output of mount: 172.17.28.5:/ovirt_production on /rhev/data-center/mnt/172.17.28.5:_ovirt__production type nfs4 (rw,relatime,vers=4.0,rsize=65536,wsize=65536,namlen=255,soft, nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,clientaddr=172.17.28.12,local_lock=none,addr=172.17.28.5) 172.17.28.5:/ovirt_hosted_engine on /rhev/data-center/mnt/172.17.28.5:_ovirt__hosted__engine type nfs4 (rw,relatime,vers=4.0,rsize=65536,wsize=65536,namlen=25 5,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,clientaddr=172.17.28.12,local_lock=none,addr=172.17.28.5) Test3: Protocol NFS4 / ExportPolicy NFS with limited IP group access In progress, but I have high hopes now. Will keep you posted. BTW.I was not able to find location in NetApp Volume where squashing is being defined, so I can not answer that one yet. Thank you.

NetApp is weird about allowing changes done to the root directory of a share. I would recommend creating a folder on the NetApp share like “rhevstor” or something so that you can chown that folder and mount the folder for the storage domain. I never had much luck mounting and using the root level of the NetApp NFS share. I also have in my notes that I set “sec=sys” as a property of my NetApp data domain which wouldn’t allow me to mount it until I input it into the RHEV manager. However, you aren’t at a point of having the RHEV manager up and running so I’m not sure how much use this would be at the moment. #mount -o sec=sys 172.17.28.5:/rhevstor /mnt/temp NFS share will fail if it isn’t accessible from all hosts, so make sure to go into each host to run #showmount -e 172.17.28.5 The ownership of the NFS share needs to be owned by vdsm:kvm. To do this, you have to manually mount the NFS share to one of the hosts temporarily then run the following command to get ownership settings setup. #mkdir /mnt/temp #mount -o sec=sys 172.17.28.5:/rhevstor /mnt/temp #chown 36:36 /mnt/temp #umount /mnt/temp Then try and run the install again. If it fails, disable NFSv3 and run again to see if it is related to NFSv4 security settings.

I don’t advise leaving it at NFSv3 but just for testing we can try it out. Also, there is some documentation on NetApp support regarding manually mounting the NFS share to change permissions then unmount. It has to be done once but after that the mounting should be fine. Do you have root squash set on NetApp?
