New subject: Install fresh 4.3 fails with mounting shared storage

30 May 2019

      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?

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

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

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]
[ INFO  ] TASK [ovirt.hosted_engine_setup : Force facts gathering]

[ 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.
