Active Administrator 8.6.3 - Web Console User Guide

Required permissions: When monitored locally and remotely, only domain user privilege is required and the user must be a part of the Performance Logs user group.

Description

Remote Differential Compression (RDC) only updates changes to files, which is useful when replicating across a wide area network.

Resolution

Enable Remote Differential Compression.

DFSRS sharing violation

Indicates that a sharing violation exists for a period greater than or equal to the specified threshold.

Requirements

•

Supported on: Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, and Windows Server 2019

•

Required permissions: When monitored locally and remotely, only domain user privilege is required and the user must be a part of the Performance Logs user group.

Description

The Active Directory Health Analyzer agent monitors the DFRS debug log for reports of sharing violations. If the sharing violation exists for a period exceeding the configured duration, the agent sets this alert condition.

One possibility for the sharing violation is that other sources may have opened the file to be replicated on the target machine.

Another possibility for a sharing violation is that other sources have open handles to the file to be replicated. Typically, programs that can instigate sharing violations are:

•

Antivirus programs

•

Disk optimization tools

•

File system policies that repeatedly apply access control list (ACL) changes

•

A user profile or personal data that is constantly in use that is placed on the replica set

•

Any other type of data that is held open for long periods by an end user, a program, or a process

Resolution

•

Rename the locked file.

•

Identify the locked files and release the handles.

FRS Encounters "ERROR_SHARING_VIOLATION" Errors When It Tries to Replicate Data That Is Still in Use

DFSRS staged file age

Indicates that the age of files in the Distributed File System Replication (DFSR) staging folder is greater than or equal to the specified threshold.

General

Requirements

•

Supported on: Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, and Windows Server 2019

•

Required permissions: When monitored locally and remotely, only domain user privilege is required and the user must be a part of the Performance Logs user group.

Description

This situation could be caused by the following factors:

•

The replication schedule is too short to allow all data to replicate to other members.

•

Network bandwidth is affecting the speed at which files replicate, causing a delay.

•

A downstream partner is unavailable due to network problems or other issues.

•

Possibly caused by a nonauthoritative restore (also called D2) on a downstream partner.

Resolution

If a D2 was not performed on a downstream partner, look for failure indicators at either the upstream or downstream partners. If you cannot find failure indicators, re-examine the schedule and network bandwidth on this connection to ensure that enough replication time is scheduled to allow the data to replicate.

DFSRS staging area disk space

Indicates that the amount of disk space allocated for staging files during replication is less than or equal to the specified threshold.

Supported on: Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, and Windows Server 2019

•

Required permissions: When monitored locally and remotely, only domain user privilege is required and the user must be a part of the Performance Logs user group.

Description

If the File Replication Service (FRS) runs out of staging disk space, replication will stop. The size of the contents of the staging areas for all active replication sets are subtracted from the user controlled size.

A low disk space condition can be due to many different things. Some possibilities are: the size of the data to be replicated is larger than the staging area, there are too many replica sets active at once, or there are files destined for one or more out-bound partners that have not been connected for a while.

Resolution

•

Increase the amount of space allowed for file staging.

•

Check replication schedules and connectivity between partners.
