#ValidationTags#CodeStyle,Messaging,FlowControl,Pipeline# function Get-DbaDiskSpace { <# .SYNOPSIS Displays disk information for all local disk on a server. .DESCRIPTION Returns a custom object with server name, name of disk, label of disk, total size, free size, percent free, block size and filesystem. By default, this function only shows drives of types 2 and 3 (removable disk and local disk). Requires Windows administrator access on SQL Servers .PARAMETER ComputerName The target computer. Defaults to localhost. .PARAMETER Credential Credential object used to connect to the computer as a different user. .PARAMETER Unit This parameter has been deprecated and will be removed in 1.0.0 All properties previously generated through this command are present at the same time, but hidden by default. .PARAMETER CheckForSql If this switch is enabled, disks will be checked for SQL Server data and log files. Windows Authentication is always used for this. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER ExcludeDrive Filter out drives - format is C:\ .PARAMETER Detailed Output all properties, will be deprecated in 1.0.0 release. Use Force Instead .PARAMETER CheckFragmentation If this switch is enabled, fragmentation of all filesystems will be checked. This will increase the runtime of the function by seconds or even minutes per volume. .PARAMETER Force Enabling this switch will cause the command to include ALL drives. By default, only local disks and removable disks are shown, and hidden volumes are excluded. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .PARAMETER WhatIf If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .NOTES Tags: Storage, Disk Author: Chrissy LeMaire (clemaire@gmail.com) & Jakob Bindslet (jakob@bindslet.dk) dbatools PowerShell module (https://dbatools.io, clemaire@gmail.com) Copyright (C) 2016 Chrissy LeMaire License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaDiskSpace .EXAMPLE Get-DbaDiskSpace -ComputerName srv0042 Get disk space for the server srv0042. .EXAMPLE Get-DbaDiskSpace -ComputerName srv0042 -Unit MB Get disk space for the server srv0042 and displays in megabytes (MB). .EXAMPLE Get-DbaDiskSpace -ComputerName srv0042, srv0007 -Unit TB Get disk space from two servers and displays in terabytes (TB). .EXAMPLE Get-DbaDiskSpace -ComputerName srv0042 -Force Get all disk and volume space information. .EXAMPLE Get-DbaDiskSpace -ComputerName srv0042 -ExcludeDrive 'C:\' Get all disk and volume space information. #> [CmdletBinding()] param ( [Parameter(ValueFromPipeline = $true)] [Alias('ServerInstance', 'SqlInstance', 'SqlServer')] [DbaInstanceParameter[]]$ComputerName = $env:COMPUTERNAME, [PSCredential]$Credential, [ValidateSet('Bytes', 'KB', 'MB', 'GB', 'TB', 'PB')] [string]$Unit = 'GB', [switch]$CheckForSql, [PSCredential]$SqlCredential, [string[]]$ExcludeDrive, [Alias('Detailed', 'AllDrives')] [switch]$CheckFragmentation, [switch]$Force, [switch][Alias('Silent')] $EnableException ) begin { Test-DbaDeprecation -DeprecatedOn 1.0.0 -Parameter Detailed Test-DbaDeprecation -DeprecatedOn 1.0.0 -Parameter AllDrives Test-DbaDeprecation -DeprecatedOn 1.0.0 -Parameter Unit $condition = " WHERE DriveType = 2 OR DriveType = 3" if (Test-Bound 'Force') { $condition = "" } # Keep track of what computer was already processed to avoid duplicates $processed = New-Object System.Collections.ArrayList <# In order to support properly identifying if a disk/volume is involved with ANY instance on a given computer #> $sqlDisks = New-Object System.Collections.ArrayList } process { foreach ($computer in $ComputerName) { if ($computer.ComputerName -notin $processed) { $null = $processed.Add($computer.ComputerName) Write-Message -Level VeryVerbose -Message "Connecting to $computer." -Target $computer.ComputerName } else { continue } try { $disks = Get-DbaCmObject -ComputerName $computer.ComputerName -Query "SELECT * FROM Win32_Volume$condition" -Credential $Credential -Namespace root\CIMv2 -ErrorAction Stop -WarningAction SilentlyContinue -EnableException } catch { Stop-Function -Message "Failed to connect to $computer." -EnableException $EnableException -ErrorRecord $_ -Target $computer.ComputerName -Continue } if ($CheckForSql) { try { $sqlServices = Get-DbaService -ComputerName $computer -Type Engine } catch { Write-Message -Level Warning -Message "Failed to connect to $computer to gather SQL Server instances, will not be reporting SQL Information." -ErrorRecord $_ -OverrideExceptionMessage -Target $computer.ComputerName } Write-Message -Level Verbose -Message "Instances found on $($computer): $($sqlServices.InstanceName.Count)" if ($sqlServices.InstanceName.Count -gt 0) { foreach ($sqlService in $sqlServices) { if ($sqlService.InstanceName -eq "MSSQLSERVER") { $instanceName = $sqlService.ComputerName } else { $instanceName = "$($sqlService.ComputerName)\$($sqlService.InstanceName)" } Write-Message -Level VeryVerbose -Message "Processing instance $($instanceName)" try { $server = Connect-SqlInstance -SqlInstance $instanceName -SqlCredential $SqlCredential if ($server.Version.Major -lt 9) { $sql = "SELECT DISTINCT SUBSTRING(physical_name, 1, LEN(physical_name) - CHARINDEX('\', REVERSE(physical_name)) + 1) AS SqlDisk FROM sysaltfiles" } else { $sql = "SELECT DISTINCT SUBSTRING(physical_name, 1, LEN(physical_name) - CHARINDEX('\', REVERSE(physical_name)) + 1) AS SqlDisk FROM sys.master_files" } $results = $server.Query($sql) if ($results.SqlDisk.Count -gt 0) { foreach ($sqlDisk in $results.SqlDisk) { if (-not $sqlDisks.Contains($sqlDisk)) { $null = $sqlDisks.Add($sqlDisk) } } } } catch { Write-Message -Level Warning -Message "Failed to connect to $instanceName on $computer.
