Re: Many warnings
Here is what you need to check.
On the NMC go to -> Devices -> Storage Nodes, check the name of the storage node in question (you have to note if it is just he hostname or with the FQDN). Then go backup to the NMC -> Configuration -> Clients. search for that storage node in here and see what name it is configured with. The name should be same as the one under the storage node that you earlier noted.
