[ovirt-users] Where to add NFS Data Storage

[Taste-Of-IT]

Hello,
i want to install self-hosted-engine with nfs storage on host and engine 
uses this storage. i tried it but i dont know where to add the nfs 
storage for data.  i first setup nfs server which is working, then added 
the nfs export dir in host setup installation, than install engine and 
dont add storage there. if i now want to add on system tab under storage 
new data storage this nfs export i got the message, that the storage is 
in use by another domain. What is the right way to use local nfs storage 
for engine?

thx
