Call "HostDatastoreSystem.CreateNasDatastore" for object "ha-datastoresystem" on ESXi X.X.x.232" failed.
NFS mount x.x.x.117:/vol/NFS_Storage failed: Unable to connect to NFS server.

Ensure that your vmkernel port can vmkping the  controller IP.

Also ensure that your exports on the nfs volume/datastore with read/write and root access to volume.

If you have VSC installed you can use this to create the datastore on the storage, it will create all the permissions for you

thanks !!

 can you confirm that i have to use a separate subnet for the VMK for management and a separate subnet for the storage traffic ?
Paul SolovyovskySenior IT AdvisorCommented:
you don't have to but it's best practice and you don't want unencrypted nfs traffic on your production network as anyone would be able to attach to your datastores.

perfect , we will put it on another subnet
