Function Get-DbaDiskSpace { <# .SYNOPSIS Displays Disk information for all local drives on a server .DESCRIPTION Returns a custom object with Server name, name of disk, label of disk, total size, free size and percent free. .PARAMETER ComputerName The SQL Server (or server in general) that you're connecting to. The -SqlServer parameter also works. .PARAMETER Unit Display the disk space information in a specific unit. Valid values incldue 'KB', 'MB', 'GB', 'TB', and 'PB'. Default is GB. .PARAMETER CheckForSql Check to see if any SQL Data or Log files exists on the disk. Uses Windows authentication to connect by default. .PARAMETER SqlCredential If you want to use SQL Server Authentication to connect. .NOTES Requires: Windows sysadmin access on SQL Servers dbatools PowerShell module (https://dbatools.io, clemaire@gmail.com) Copyright (C) 2016 Chrissy LeMaire This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
