I'm trying to get an ISO domain configured in a new RHEVM manager. I did 
not configure it during the initial ovirt-engine-setup, and am manually 
configuring it after the fact.

I created an NFS share in /var/lib/exports/iso and dropped a couple of 
files in there from elsewhere, just for testing purposes.

On a client system, I can mount the NFS share, but it appears empty.

On the RHEV manager when I try to add an ISO domain, I get this error 
message:

"Error while executing action Add Storage Connection: Permission 
settings on the specified path do not allow access to the storage.
Verify permission settings on the specified storage path."

I suspect the selinux permissions aren't set right. This is what they 
are currently configured to:

On the folder itself
[root@hostname iso]# ll -dZ .
drwxr-xr-x. root root system_u:object_r:nfs_t:s0

On the two files in the folder:

[root@hostname iso]# ll -Z
-rwxrw-rw-. root root unconfined_u:object_r:nfs_t:s0 
sosreport-LogCollector-20170117092344.tar.xz
-rwxrw-rw-. root root unconfined_u:object_r:nfs_t:s0 test.txt

Is this correct? If not what should they be set to?

Thanks

Paul
