Prerequisites

  • An AWS account with administrative level access
  • An Amazon FSx for Windows File Server
  • Windows EC2 instances running the DFS namespaces role

WARNING!! This workshop environment will exceed your free-usage tier. You will incur charges as a result of building this environment and executing the scripts included in this workshop. Delete all AWS resources created during this workshop so you don’t continue to incur additional compute and storage charges.


Setup DFS

You must first complete Prerequisites and the previous step Restore backup

Step 9.1: Setup a DFS Namespace for consolidation

  • From the Amazon EC2 Console, copy the Public DNS (IPv4) name of the NSS1-fsx-... instance
  • Launch your remote desktop application to log on to the Windows EC2 instance you created in the previous workshop
  • Log on to the NSS1-fsx-... instance using following AD credentials
Username Password
[email protected] (e.g. [email protected]) The Microsoft Active Directory (MAD) password you entered as a parameter when you launched the prerequisites CloudFormation stack
  • Make a note of the computer name of the instance (e.g. $NSS1 = "EC2AMAZ-")

  • From the Amazon EC2 Console, copy the Public DNS (IPv4) name of the NSS2-fsx-... instance

  • Launch your remote desktop application to log on to the Windows EC2 instance you created in the previous workshop

  • Log on to the NSS2-fsx instance using following AD credentials

Username Password
[email protected] (e.g. [email protected]) The Microsoft Active Directory (MAD) password you entered as a parameter when you launched the prerequisites CloudFormation stack
  • Make a note of the computer name of the instance (e.g. $NSS2 = "EC2AMAZ-")

  • From either Namespace Server instance (e.g. NSS1 or NSS2), complete the following steps

Complete the following steps logged on to one of the namespace instances

  • Access the DFS management console. Open the Start menu and type dfsmgmt.msc and print the enter/return key.

  • Connect to a new namespace. Select Action the choose New Namespace...

  • Browse and select one of the two namespace servers and choose Next.

  • Enter the name of the namespace (e.g. corp).

  • Set the permissions. Choose Edit Settings and set the appropriate permissions based on your requirements. Choose Next.

  • Leave the default Domain-based namespace option selected.

  • Leave the Enable Windows Server 2008 mode option selected.

  • Choose Next.

  • Review the namespace settings and choose Create.

  • With the newly created namespace selected choose Action then Add Namespace Server....

  • From the Add Namespace Server window, choose Browse... and select the other namespace server.

  • Select Edit Settings... and set the appropriate permissions based on your requirements. Choose OK.

  • Context-click the namespace you just created and choose New Folder....

  • Enter the name of the folder (e.g. share) and choose Add....

  • Enter the DNS name of the file system share in UNC format (e.g. \fs-0123456789abcdef.example.com\share) and choose OK.

  • Use the table below and repeat the steps above for the other shares for the other shares.

Share name
data
finance
sales
marketing

Step 9.2: Access the new file shares

  • Open File Explorer
  • Type the UNC path to one of the new namespace (e.g. \\example.com\corp\)
  • Access all the new shares created above (e.g. \data, \finance, \sales, marketing)
  • Can we read and write to all shares?

Step 9.3: Setup a DFS Replication

Complete the following steps logged on to one of the namespace instances

  • These steps will setup DFS replication, replicating the default file share (/share) of the first file system you created to the second file system you created from the restore.

  • Open a PowerShell window as an Administrator

  • Create a DFS replication group and folder

$Group = "Group" # e.g. "ReplicationGroup"
$Folder = "Folder" # e.g. "folder"

New-DfsReplicationGroup -GroupName ${Group}
Grant-DfsrDelegation -GroupName ${Group} –AccountName "FSxAdmins" –Force
New-DfsReplicationFolder -GroupName ${Group} -FolderName ${Folder}
  • Determine the Active Directory computer name associated with the write file system and the first read file system.
$FirstFSDnsName = "DNS Name of the source file system" # e.g. "fs-abcdef0123456789.example.com"
$RestoredFSDnsName = "DNS Name of the restored file system" # e.g. "fs-0123456789abcdef.example.com"
$FirstFSComputerName = (Resolve-DnsName ${FirstFSDnsName} -Type CNAME).NameHost
$ResotredFSComputerName = (Resolve-DnsName ${RestoredFSDnsName} -Type CNAME).NameHost
  • Add your two file systems as members of the DFS Replication group.
Add-DfsrMember -GroupName ${Group} -ComputerName ${FirstFSComputerName}
Add-DfsrMember -GroupName ${Group} -ComputerName ${RestoredFSComputerName}
  • Add the local path of the default file share (e.g. D:\share) for each file system to the DFS Replication group. In this workshop, the first file system will serve as the primary member, meaning that its contents will initially be synced to the restored file system.
$FirstFSReplicationPath = "D:\Share"
$RestoredFSReplicationPath = "D:\Share"

Set-DfsrMembership –GroupName ${Group} –FolderName ${Folder} –ContentPath ${FirstFSReplicationPath} –ComputerName ${FirstFSComputerName} –PrimaryMember $True -Force
Set-DfsrMembership –GroupName ${Group} –FolderName ${Folder} –ContentPath ${RestoredFSReplicationPath} –ComputerName ${RestoredFSComputerName} –PrimaryMember $False -Force
  • Add a connection between the file shares.
Add-DfsrConnection -GroupName ${Group} -SourceComputerName ${FirstFSComputerName} -DestinationComputerName ${RestoredFSComputerName}
  • Map a drive to the default file shares of both file systems
  • Open each mapped drive in a separate File Explorer window
  • It may take 10-15 minutes for replication to start.
  • Once the replication is complete, test creating files on one file system and see them get replicated to the other.

Tear-down

Delele all the resources you created in this workshop

  • Delete both Amazon WorkSpaces
  • Once the WorkSpaces are deleted you must also register WorkSpaces from Active Directory
  • Remove the inbound rule referencing the Amazon WorkSpaces Security Group from the VPC's default security group
  • Terminate the Windows EC2 instance you launched
  • Terminate the Amazon Linux EC2 instance you launched
  • Delete the file system backups
  • Delete the both file systems
  • Delete the CloudFormation stack
