Did you have or setup a vSAN Cluster ?

It claims there is no space in the vSAN datastore.

Someone enabled vSAN on your cluster (I think) or you wouldn't be getting this error.

To check if it's enabled, use the vSphere client -> Hosts & Clusters -> select the cluster with the error, click Manage tab, click settings -> Virtual SAN  from the settings drop down. Click Edit

Does it show enabled?

If it's enabled, try turning off Virtual SAN.

Use caution if you're unsure and other people have access to your virtual data center.  

There are several requirements that must be met before configuring vSAN from hardware to networking. Here's a good KB to review if you are exploring vSAN.

You've not recently moved any ESXi hosts into your cluster, from another cluster ?

How did this error start appearing ?

actually before that these hosts were managing by another vcenter which was having a cluster and then i disassociate them from that vcenter and build new vcenter with different ip and name and add the host again to it.

That is the issue then.

A previous ESXi host, was part of a vSAN. Do you want to use vSAN in the future?

That's

1. why you have a vSAN datastore.

2. why you have vCenter error messages about vSAN.

I would recommend that you rebuild the ESXi server, which has the vSAN datastore attached.

You could try these articles

http://www.virtuallyghetto.com/2013/09/additional-steps-required-to-completely.html

To be honest, it's quicker to rebuild your ESXi host, which was part of a vSAN.

Remove the Host with the vSAN datastore from vCenter Server.

Does the error message disappear?

It does look like it has or thinks vSAN has been enabled on this host.

Does the error message disappear when you remove the host with the vSANdatastore from vCenter ?

via the web client, do you see a warning within the VSAN Configuration page stating there is a "Misconfiguration detected" which is expected?

Did you remove the host from vCenter Server ?

(disconnect will not do it, it needs to be removed!).

Can you screenshot your environment from vSphere Client
