Hey Shanii,
Correct, this is exactly what I do/did.
I did “umount /mnt/rhevstore” but I mentioned NFS storage path in order to be precise in
description.
Thing is that I am able to mount it, as well as oVirt during Host provisioning. I was even
able to create VMs on it from same Hypervisor.
As far as I remember, I was able to write to the storage and create a random file.
I will give it second attempt.

Basically, I meant to verify the access by ssh, but I want to verify something following
your detailed reply:
According to [1], in order to set a NetApp NFS server, the required steps should look like
this:
# mount NetApp_NFS:/path/to/export /mnt
# chown -R 36.36 /mnt
# chmod -R 755 /mnt
# umount /mnt
Which is quite similar to the steps you've mentioned, except the last step of
unmounting:
Unmount the 10.214.13.64:/ovirt_production
I think that you had to unmount /mnt/rhevstore instead.
Can you please verify?

Hi Shani,
Thank you for your reply, but
How do I do that?
Reason why I am asking is following:
Hosts 2,3,4 do not have that issue. Host 1 and 5 do.
What I learned previously is that when using Netapp based NFS, which we are, it’s required
to before provisioning SHE and/or just adding a Host to a pool, it’s required to execute
following steps:
Create random dir on a host:
- mkdir /mnt/rhevstore
Mount netapp volume to the dir
- mount -o sec=sys -t nfs 10.214.13.64:/ovirt_production /mnt/rhevstore
Set ownership to vdsm:kvm (36:36):
- chown -R vdsm:kvm /mnt/rhevstore/*
Unmount the 10.214.13.64:/ovirt_production
I do not expect the above ownership actions need to be done initially on each host, before
starting the deployment, otherwise it would be practically impossible to expand the Host
pool.
All 5 hosts are provisioned in same way. How? I am using foreman to provision these
servers, so they are built of same kickstart hostgroup template.
I even installed ovirt-hosted-engine-setup package to make sure all required packages,
users and groups are in place before adding host to oVirt via UI or Ansible.
Is it possible that we if I am already using or heavily using the mentioned volume via
Hosts already added to oVirt pool, that ownership actions executed,on host about to be
added to the pool, will fail to complete setting ownership on all required files on the
volume?
To repeat the question above: How do I make sure Host can read metadata file of the
storage volume?
Kindly awaiting your reply.
All best,
Marko Vrgotic

Hi Marko,
Is seems that there's a connectivity problem with host 10.210.13.64.
Can you please make sure the metadata under

Can you help me understanding why is this being reported?
This setup is:
5HOSTS, 3 in HA
SelfHostedEngine

NFS based Netapp storage, version 4.1

tmpfs on /run/user/0 type tmpfs

First mount is SHE dedicated storage.
Second mount “ovirt_produciton” is for other VM Guests.
Kindly awaiting your reply.
