This object monitors whether DFS Replication is successful in cleaning up (making additional space in) the staging folder for a replicated folder. If cleanup fails, this monitor creates a Warning alert. It does so by looking for the presence of DFS Replication Event 4206.
An unhealthy state of this monitor indicates that DFS Replication failed to clean up a staging folder. This can occur for the following reasons:
The staging folder quota is set too low for the amount of data being replicated.
The volume hosting the staging folder doesn’t have sufficient available disk space.
Another application or service (such as an antivirus application) is accessing files in the staging folder.
Wait for staging folder cleanup to complete
No action is required.
When the size of the staging folder reaches the staging folder quota limit, DFS Replication automatically attempts to clean up the staging folder by deleting old files. After the cleanup operation is complete, replication resumes.
Note: If this monitor frequently enters an unhealthy state, or to optimize performance, increase the staging folder quota.
If a quota (NTFS disk quota or File Server Resource Manager quota) is limiting the affected folder or volume, consider increasing the quota size. To adjust folders created with File Server Resource Manager, see Quota Management (http://go.microsoft.com/fwlink/?LinkId=187098). To adjust NTFS disk quotas, use the Fsutil quota command, as discussed in FSutil quota (http://go.microsoft.com/fwlink/?LinkId=187104).
Increase available disk space
If the volume hosting the staging folder or debug log files is low on disk space, increase the available disk space on the volume, increase the size of the volume, or change the path of the staging folder to a volume with more available disk space.
To manually check the amount of available disk space, open a command prompt window and type the following command, where <servername> is the name of the server hosting the affected folder and <domain\user> is your user name:
WMIC /node: "<servername>" /user: <domain\user> volume list status.
After freeing up space, restart the DFS Replication service.
This monitor automatically resets to a healthy state when the issue is resolved.
