I have the same issue with a new deployment. NFS datastores of one of my two filers are not well translated to NetApp volumes. In fact they were ok during a short time but suddently they changed to Non hosted on OnTap... So now protection is not working anymore... (the 4 lasts in the picture)
I re-install the host package and remove/re-add multiple times the Host Service. Nothing changes.
There's no communication issue between OC core and host when I look to dfm hs diag.
"dfm report view nfs-exports" give me correct information:
Object ID Type
Anonymous User ID No SUID Read-Only Access Read-Write Access Root Access
