Hi there - brand new to Rockstor but so far I’m really liking it! It completely resolved my issue with ESXi giving me terrible disk performance when connected locally 
My use case testing for now is leveraging RockStor as an NFS server for holding datastores for my ESXi server. I went through setting up my 2x2TB HDD’s in Raid 0 and then creating the Share + NFS export however, when I attempt to create/connect the datastore on the ESXi side, it seems to successfully mount but I cant actually browse or look at the datastore, let alone create files in it.
I do the same process for NSF3 in ESXi and it works…the caveat being that I seem to have to change the share permissions to allow ‘other’.
So my question is…what ‘user’ do I put into the Username/Pass field in ESXi when connecting via NSF4? I tried copying what the ‘Share’ ownership says in Rockstor’s UI but that doesn’t seem to work. Any guidance is appreciated.
