NFS service on cluster with shadow copies enabled

-

we have windows 2012 r2 file server in cluster. there no cluster shared volume (because user file server resource manager , nfs, not supported csv)
"file server general use"

we install role "server nfs".  since created first nfs share resource in cluster, new resource automatically created in file cluster role : network file system

we enabled shadow copies volume shares (nfs , smb share). use default schedule settings shadow copies, twice day.

after ~1 month, failover role on node, , noticed resource network file system take long time come online. long goes in failed state... other resources working well. if wait long enough, resource become in online state eventually... 15 minutes. 

in windows event logs, in servicesfornfs-server logs, can see operational log filled operation "created volume", "destroyed volume", "discovered volume" etc... , these operations take long time during failover of cluster. when finished, resource become online.

i tried deactivate shadow copies on volume. , failover of nfs working fast !!! nfs resource online @ same time of others resources.

so obvioulsy nfs not work shadow copies! (on cluster)

does else figured issue out ? or has idea cause of issue??
need have shadow copies on volume !

thanks !
