I have SVM scope NDMP backup on 2 nodes in cluster and it has been working for a while

We added 2 more nodes in the cluster and the filesystem from these 2 nodes (same SVM) are failing backups

Vertias NDMP error 99 (client can connect and browse the filesystem to select it for backup)

There is gotta to be something related to new nodes only, but I cannot put my finger on it
