Unable to mount hosted_storage domain on newly added Host

Latest response

Hi community,
I have RHEV self-hosted engine installed on a single server. The virtual disk for the engine is located at NFS storage domain "hosted_storage". NFS server supports only NFSv4.
During initial installation of the hosted-engine I was asked about NFS version I would like to use (and I chose v4), thus single server host I ran the installation on also mount this NFS storage domain using v4.
Now, when I tried to add one more host (second hw server), process fails on the stage of mounting hosted_storage domain, since its nfs version option is set to v3 (please see the image at the end of this post)

I tried to use ovirt-shell to update nfs client options to use version 4, however it did not reflect any effect of this command:

How would I change NFS version to v4 for hosted_storage domain without setting it to Maintenance mode?
