Marko,

No problem, here are some other things to check as well.

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.

Best regards,

Hi Roy,

I will run all those tests tomorrow morning  (Amsterdam TimeZone) and reply back with results.

Regarding NetApp documentation you mentioned below, I assume it should be enough to just “google” for it.

Thank you very much for jumping in, we really appreciate it.

Kind regards,

Marko Vrgotic

Marko,

Can you try disabling NFSv4 on the NetApp side for testing and rerun the installer? 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?

Best regards,

Hi Roy,

Sure, here is the output:

Last login: Wed May 29 17:25:30 2019 from ovirt-engine.avinity.tv

[root@ovirt-hv-03 ~]# showmount -e 172.17.28.5

Export list for 172.17.28.5:

drwxr-xr-x. 3 vdsm kvm 17 May 29 17:11 ..

In addition, if it helps, here is the list of shares/mount points from Netapp side, behind the 172.17.28.5 IP:

Kind regards

Marko,

Can you run the following commands and let us know the results.

showmount -e 172.17.28.5

ls -la /rhev/data-center/mnt/

Dear oVIrt,

We are trying to deploy new setup with Hosted-Engine , oVirt version 4.3.

Volume is on the Netapp, protocol NFS v4.

Upon populating shared storage information and path:

          Please specify the storage you would like to use (glusterfs, iscsi, fc, nfs)[nfs]: nfs

          Please specify the nfs version you would like to use (auto, v3, v4, v4_1)[auto]: auto

          Please specify the full shared storage connection path to use (example: host:/path): 172.17.28.5:/ovirt_hosted_engine

Following is displayed on the screen:

[ INFO  ] Creating Storage Domain

[ INFO  ] TASK [ovirt.hosted_engine_setup : Execute just a specific set of steps]

[ INFO  ] ok: [localhost]

[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Fault reason is \"Operation Failed\". Fault detail is \"[General Exception]\". HTTP response code is 400."}

Even with this error – storage gets mounted on the Host:

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=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,clientaddr=172.17.28.11,local_lock=none,addr=172.17.28.5)

But playbook execution fails and we can not proceed with install.

Please advise.

Kindly awaiting your reply.
