[one-users] VMware VMFS vs NFS

[Dmitri Chebotarov]

Tino

The reason for NFS is hardware only provides NFS exports (NetApp filer, no
iSCSI license). 

I may need a little bit more help.
I've added a datastore (id 139) as Vmware VMFS, checked that both DS_MAD
and TS_MAD set to 'vmfs', also set Base Path to '/vmfs/volumes' (before
adding DS).

When ONED tries to monitor new Vmware VMFS datastore I get the error:
