Widelinks are not accessible from Mac clients
When a user attempts to connect to a share using widelinks from a Mac OS X
client, the attempt fails. Widelinks are not accessible from Mac OS X clients.
Empty CIFS/SMB2.x change notifications
CIFS/SMB2.x clients connected to the storage system might request to be
notified about changes to a particular directory. In certain situations, the
notifications that Data ONTAP returns are empty.
Data ONTAP collects all notifications that occur within 500 milliseconds after
an event is generated to avoid subsequent change notify requests for every
single such event. If the maximum capacity of the buffer that is allocated to
hold these notifications is reached, Data ONTAP responds with an empty
notification.
To work around this issue, you can decrease the time period for accumulating
events. Decreasing the time period reduces the chance of maxing out the
buffer and receiving empty change notifications.
To decrease the time period, enter the following command:
setflag smb_boxcar_expire_ms time
time is the length of the time period in milliseconds.
By reducing this time period, Data ONTAP returns change notification
responses quicker and with fewer events per response. While this might not
completely eliminate empty notifications, a properly reduced time period
reduces them significantly.
Due to the reduced number of events returned with each change notification
response, clients have to send more change notify requests to obtain all
events.
