.SYNOPSIS

Shrinks FSLogix Profile and O365 dynamically expanding disk(s).

.DESCRIPTION

FSLogix profile and O365 virtual hard disks are in the vhd or vhdx file format. By default, the disks created will be in Dynamically Expanding format rather than Fixed format. This script does not support reducing the size of a Fixed file format.

Dynamically Expanding disks do not natively shrink when the volume of data within them reduces, they stay at the 'High water mark' of historical data volume within them.

This means that Enterprises can wish to reclaim whitespace inside the disks to keep cost down if the storage is cloud based, or make sure they don’t exceed capacity limits if storage is on-premises.

This Script is designed to work at Enterprise scale to reduce the size of thousands of disks in the shortest time possible.

This script can be run from any machine in your environment it does not need to be run from a file server hosting the disks. It does not need the Hyper-V role installed.

Powershell version 5.x and 7 and above are supported for this script. It needs to be run as administrator due to the requirement for mounting disks to the OS where the script is run.

This tool is multi-threaded and will take advantage of multiple CPU cores on the machine from which you run the script. It is not advised to run more than 2x the threads of your available cores on your machine. You could also use the number of threads to throttle the load on your storage.

Reducing the size of a virtual hard disk is a storage intensive activity. The activity is more in file system metadata operations than pure IOPS, so make sure your storage controllers can handle the load. The storage load occurs on the location where the disks are stored not on the machine where the script is run from. I advise running the script out of hours if possible, to avoid impacting other users on the storage.

With the intention of reducing the storage load to the minimum possible, you can configure the script to only shrink the disks where you will see the most benefit. You can delete disks which have not been accessed in x number of days previously (configurable). Deletion of disks is not enabled by default. By default the script will not run on any disk with less than 5% whitespace inside (configurable). The script can optionally also not run on disks smaller than xGB (configurable) as it’s possible that even a large % of whitespace in small disks won’t result in a large capacity reclamation, but even shrinking a small amount of capacity will cause storage load.

The script will output a csv in the following format:

"Name","DiskState","OriginalSizeGB","FinalSizeGB","SpaceSavedGB","FullName"

"Profile_user1.vhdx","Success","4.35","3.22","1.13",\\Server\Share\ Profile_user1.vhdx "

"Profile_user2.vhdx","Success","4.75","3.12","1.63",\\Server\Share\ Profile_user2.vhdx

Possible Information values for DiskState are as follows:

Success Disk has been successfully processed and shrunk

Ignored Disk was less than the size configured in -IgnoreLessThanGB parameter

Deleted Disk was last accessed before the number of days configured in the -DeleteOlderThanDays parameter and was successfully deleted

DiskLocked Disk could not be mounted due to being in use

LessThan(x)%FreeInsideDisk Disk contained less whitespace than configured in -RatioFreeSpace parameter and was ignored for processing

Possible Error values for DiskState are as follows:

FileIsNotDiskFormat Disk file extension was not vhd or vhdx

DiskDeletionFailed Disk was last accessed before the number of days configured in the -DeleteOlderThanDays parameter and was not successfully deleted

NoPartitionInfo Could not get partition information for partition 1 from the disk

PartitionShrinkFailed Failed to Optimize partition as part of the disk processing

DiskShrinkFailed Could not shrink Disk

PartitionSizeRestoreFailed Failed to Restore partition as part of the disk processing

If the diskstate shows an error value from the list above, manual intervention may be required to make the disk usable again.

If you inspect your environment you will probably see that there are a few disks that are consuming a lot of capacity targeting these by using the minimum disk size configuration would be a good step. To grab a list of disks and their sizes from a share you could use this oneliner by replacing <yourshare> with the path to the share containing the disks.

Get-ChildItem -Path <yourshare> -Filter "*.vhd*" -Recurse -File | Select-Object Name, @{n = 'SizeInGB'; e = {[math]::round($_.length/1GB,2)}}

All this oneliner does is gather the names and sizes of the virtual hard disks from your share. To export this information to a file readable by excel, use the following replacing both <yourshare> and < yourcsvfile.csv>. You can then open the csv file in excel.

Get-ChildItem -Path <yourshare> -Filter "*.vhd*" -Recurse -File | Select-Object Name, @{n = 'SizeInGB'; e = {[math]::round($_.length/1GB,2)}} | Export-Csv -Path < yourcsvfile.csv>

.NOTES

Whilst I work for Microsoft and used to work for FSLogix, this is not officially released software from either company. This is purely a personal project designed to help the community. If you require support for this tool please raise an issue on the GitHub repository linked below

.PARAMETER Path

The path to the folder/share containing the disks. You can also directly specify a single disk. UNC paths are supported.

.PARAMETER Recurse

Gets the disks in the specified locations and in all child items of the locations

.PARAMETER IgnoreLessThanGB

The disk size in GB under which the script will not process the file.

.PARAMETER DeleteOlderThanDays

If a disk ‘last access time’ is older than todays date minus this value, the disk will be deleted from the share. This is a permanent action.

.PARAMETER LogFilePath

All disk actions will be saved in a csv file for admin reference. The default location for this csv file is the user’s temp directory. The default filename is in the following format: FslShrinkDisk 2020-04-14 19-36-19.csv

.PARAMETER PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any pipeline output.

.PARAMETER ThrottleLimit

Specifies the number of disks that will be processed at a time. Further disks in the queue will wait till a previous disk has finished up to a maximum of the ThrottleLimit. The default value is 8.

.PARAMETER RatioFreeSpace

The minimum percentage of white space in the disk before processing will start as a decimal between 0 and 1 eg 0.2 is 20% 0.65 is 65%. The Default is 0.05. This means that if the available size reduction is less than 5%, then no action will be taken. To try and shrink all files no matter how little the gain set this to 0.

.INPUTS

You can pipe the path into the command which is recognised by type, you can also pipe any parameter by name. It will also take the path positionally

.OUTPUTS

This script outputs a csv file with the result of the disk processing. It will optionally produce a custom object with the same information

.EXAMPLE

C:\PS> Invoke-FslShrinkDisk -Path c:\Profile_user1.vhdx

This shrinks a single disk on the local file system

.EXAMPLE

C:\PS> Invoke-FslShrinkDisk -Path \\server\share -Recurse

This shrinks all disks in the specified share recursively

.EXAMPLE

C:\PS> Invoke-FslShrinkDisk -Path \\server\share -Recurse -IgnoreLessThanGB 3

This shrinks all disks in the specified share recursively, except for files under 3GB in size which it ignores.

.EXAMPLE

C:\PS> Invoke-FslShrinkDisk -Path \\server\share -Recurse -DeleteOlderThanDays 90

This shrinks all disks in the specified share recursively and deletes disks which were not accessed within the last 90 days.

.EXAMPLE

C:\PS> Invoke-FslShrinkDisk -Path \\server\share -Recurse -LogFilePath C:\MyLogFile.csv

This shrinks all disks in the specified share recursively and changes the default log file location to C:\MyLogFile.csv

.EXAMPLE

C:\PS> Invoke-FslShrinkDisk -Path \\server\share -Recurse -PassThru

Name: Profile_user1.vhdx

DiskState: Success

OriginalSizeGB: 4.35

FinalSizeGB: 3.22

SpaceSavedGB: 1.13

FullName: \\Server\Share\ Profile_user1.vhdx

This shrinks all disks in the specified share recursively and passes the result of the disk processing to the pipeline as an object.

.EXAMPLE

C:\PS> Invoke-FslShrinkDisk -Path \\server\share -Recurse -ThrottleLimit 20

This shrinks all disks in the specified share recursively increasing the number of threads used to 20 from the default 8.

.EXAMPLE

C:\PS> Invoke-FslShrinkDisk -Path \\server\share -Recurse -RatioFreeSpace 0.3

This shrinks all disks in the specified share recursively while not processing disks which have less than 30% whitespace instead of the default 15%.

<#

.SYNOPSIS

Function to control parallel processing using runspaces

.DESCRIPTION

Function to control parallel processing using runspaces

Note that each runspace will not have access to variables and commands loaded in your session or in other runspaces by default.

This behaviour can be changed with parameters.

.PARAMETER ScriptFile

File to run against all input objects. Must include parameter to take in the input object, or use $args. Optionally, include parameter to take in parameter. Example: C:\script.ps1

.PARAMETER ScriptBlock

Scriptblock to run against all computers.

You may use $Using:<Variable> language in PowerShell 3 and later.

The parameter block is added for you, allowing behaviour similar to foreach-object:

Refer to the input object as $_.

Refer to the parameter parameter as $parameter

.PARAMETER InputObject

Run script against these specified objects.

.PARAMETER Parameter

This object is passed to every script block. You can use it to pass information to the script block; for example, the path to a logging folder

Reference this object as $parameter if using the scriptblock parameterset.

.PARAMETER ImportVariables

If specified, get user session variables and add them to the initial session state

.PARAMETER ImportModules

If specified, get loaded modules and pssnapins, add them to the initial session state

.PARAMETER Throttle

Maximum number of threads to run at a single time.

.PARAMETER SleepTimer

Milliseconds to sleep after checking for completed runspaces and in a few other spots. I would not recommend dropping below 200 or increasing above 500

.PARAMETER RunspaceTimeout

Maximum time in seconds a single thread can run. If execution of your code takes longer than this, it is disposed. Default: 0 (seconds)

WARNING: Using this parameter requires that maxQueue be set to throttle (it will be by default) for accurate timing. Details here:

http://gallery.technet.microsoft.com/Run-Parallel-Parallel-377fd430

.PARAMETER NoCloseOnTimeout

Do not dispose of timed out tasks or attempt to close the runspace if threads have timed out. This will prevent the script from hanging in certain situations where threads become non-responsive, at the expense of leaking memory within the PowerShell host.

.PARAMETER MaxQueue

Maximum number of powershell instances to add to runspace pool. If this is higher than $throttle, $timeout will be inaccurate

If this is equal or less than throttle, there will be a performance impact

The default value is $throttle times 3, if $runspaceTimeout is not specified

The default value is $throttle, if $runspaceTimeout is specified

.PARAMETER LogFile

Path to a file where we can log results, including run time for each thread, whether it completes, completes with errors, or times out.

.PARAMETER AppendLog

Append to existing log

.PARAMETER Quiet

Disable progress bar

.EXAMPLE

Each example uses Test-ForPacs.ps1 which includes the following code:

param($computer)

if(test-connection $computer -count 1 -quiet -BufferSize 16){

$object = [pscustomobject] @{

Computer=$computer;

Available=1;

Kodak=$(

if((test-path "\\$computer\c$\users\public\desktop\Kodak Direct View Pacs.url") -or (test-path "\\$computer\c$\documents and settings\all users\desktop\Kodak Direct View Pacs.url") ){"1"}else{"0"}

)

}

}

else{

$object = [pscustomobject] @{

Computer=$computer;

Available=0;

Kodak="NA"

}

}

$object

.EXAMPLE

Invoke-Parallel -scriptfile C:\public\Test-ForPacs.ps1 -inputobject $(get-content C:\pcs.txt) -runspaceTimeout 10 -throttle 10

Pulls list of PCs from C:\pcs.txt,

Runs Test-ForPacs against each

If any query takes longer than 10 seconds, it is disposed

Only run 10 threads at a time

.EXAMPLE

Invoke-Parallel -scriptfile C:\public\Test-ForPacs.ps1 -inputobject c-is-ts-91, c-is-ts-95

Runs against c-is-ts-91, c-is-ts-95 (-computername)

Runs Test-ForPacs against each

.EXAMPLE

$stuff = [pscustomobject] @{

ContentFile = "windows\system32\drivers\etc\hosts"

Logfile = "C:\temp\log.txt"

}

$computers | Invoke-Parallel -parameter $stuff {

$contentFile = join-path "\\$_\c$" $parameter.contentfile

Get-Content $contentFile |

set-content $parameter.logfile

}

This example uses the parameter argument. This parameter is a single object. To pass multiple items into the script block, we create a custom object (using a PowerShell v3 language) with properties we want to pass in.

Inside the script block, $parameter is used to reference this parameter object. This example sets a content file, gets content from that file, and sets it to a predefined log file.

.EXAMPLE

$test = 5

1..2 | Invoke-Parallel -ImportVariables {$_ * $test}

Add variables from the current session to the session state. Without -ImportVariables $Test would not be accessible

.EXAMPLE

$test = 5

1..2 | Invoke-Parallel {$_ * $Using:test}

Reference a variable from the current session with the $Using:<Variable> syntax. Requires PowerShell 3 or later. Note that -ImportVariables parameter is no longer necessary.
