Mounting NFS datastores with different IP address one different ESXi Hosts 讓不同的ESXi host使用不同的IP掛載同一個NFS Target
I have a small vSphere environment, the NAS has 4 NIC ports, 3 ESXi client direct connect to NAS without switch/hub by different IPs. vCenter thake them as different NFS datastore, because of different UUIDs.
山不轉路轉，路不轉人轉。 ESXi底層也是Linux，所以網路查詢host對應ip時會先找 /etc/hosts 。 用ssh 登入console，用vi修改 /etc/hosts 加上類似以下這行：
Use ssh login into console, edit /etc/hosts by vi. Every ESXi host use correspond IP, then mount NFS storage by hostname.
如果現有VM在上面，必須在ESXi host先取消註冊才能重新掛載。
If there are VMs on a NFS datastore, you have to unregister them from ESXi host.
A UUID mismatch between two datastores occurs because the UUID is based on a hash of the NFS Server and Path, as seen by running esxcfg-nas. If you have specified the NFS server information using different methods on different hosts, then the hash value, and ultimately the UUIDs will be different.我有一個小型的vSphere環境，其中1座4埠網路NAS和3台ESXi使用不同網段IP直接連接到NAS。但是vCenter認為它們是不同的NFS datastore，因為產生的hash和UUID不同，詳見 VMware KB1005930。

172.16.1.1 nas每一台 ESXi 都要做，用對應的IP設定在 /etc/hosts ，使用hostname去mount NFS，收工！
