Recently I was trying to get an ESX blade to connect to a NAS data store. 2 Other blades had happily connected to this data store, and this blade was already connected to a different data store, but when ever I tried to connect to this particular store, I got this error:
NFS Error: unable to Mount filesystem: Unable to connect to NFS server
So I struggled with this problem for quite some time, until I found the solution - Name Resolution. Now firstly, I would like to point out that I was connecting to this blade from ESX by IP, not name, so didn't think resolution was a problem. However what ended up fixing this was ensuring that the NAS could resolve the ESX blade by name. I'm not sure why this was needed, as the other 2 blades had worked fine without needing proper name resolution setup, as had the connection to the other blade, but I added an entry in DNS for the ESX blade, and hey presto, it works.
