I've just been hit with this. How did you solve it?




This issue is mentioned in this KB. However, only the EMS logs will reveal if this is an exact issue.


Snapvault (XDP) failed with Error Volume access error(Permission denied):


This issue might occur if SnapVault transfers are carried out when both the source and destination volumes experience heavy NFS traffic.

Manual update of XDP relationships using the command:
# snapmirror update -destination-path <vserver_name>:<volume_name>

Check if you see any errors similar to the one mentioned in the kB:
::*> event log show -message-name wafl.repl.send.inode.err*


Try updating after some time, in the mean time check the NFS traffic IOPS/MBPS.


If you have OCUM/AUM, you can easily narrow down how the traffic's been for the  volume concerend.
