Mount and umount the export on the client. After configuring and running I/O operations to SMB shares and NFS exports events such as an appliance or NAS server reboot, or a file system unmount or remount may cause some negative values to appear in the saved file system performance statistics exported from PowerStore Manager (GUI). None After a request is sent from the REST API with an incorrect GUID, the error message returned displays the invalid UID: 00000000-0000-0000-0000000000000000. Ignore the UID in the error message and retry the request with the correct GUID. Uploading configuration files to a NAS server, which were edited in WordPad, does not work as expected. Use vim or Notepad to edit configuration files before uploading them to the NAS server. The following alert is sent during upgrade "NAS server [server name] fault tolerance is degraded due to NAS upgrade procedure on a peer NAS cluster node." However, once upgrade is complete the alert is not always automatically cleared. After upgrade completes, acknowledge the alert to clear it. The "NAS node is down," major alert may be seen after changing the Cluster MTU value. Changing the MTU value may cause degradation or disruption in NAS (file) services. Wait for the alert to clear before performing any further NAS (File) operations. Under rare circumstances, NAS services could be disrupted, if the appliance is close to reaching the maximum used data capacity. Take one of the following actions on the appliance on which the NAS service is installed: add capacity to the appliance (for example, add drives or expansion enclosures), increase free capacity on the system (for example, deleting unused snapshots, volumes) , or migrate data off the system. 10 Known Issues
