VMWare ESX: NFS Error: unable to Mount filesystem: Unable to connect to NFS server
Monday, March 1st, 2010
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 work.
So if you come across this issue, ensure your NAS can resolve your ESX server, either in your DNS server or a local host file.
