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, percent free, block size and filesystem. By default, this funtion only shows drives of type 2 and 3 (removable disk and local disk). Requires: Windows administrator access on SQL Servers .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 include 'Bytes', '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. .PARAMETER CheckFragmentation Includes a check for fragmentation in all filesystems. This will increase the runtime of the function, as a fragmentation check can take seconds or even minutes for a single volume. .PARAMETER AllDrives Without this switch, the function will only return information about drivetype 2 and 3 (removable disk and local disk). When this switch is used, data from all types of disks are returned: Value Type of disk 0 Unknown 1 No Root Directory 2 Removable Disk 3 Local Disk 4 Network Drive 5 Compact Disk 6 RAM Disk https://msdn.microsoft.com/en-us/library/aa394515.aspx .PARAMETER Detailed Includes information about filesystem (FAT32, NTFS, ReFS, etc.), as well as the information provided by -CheckForSql and -AllDrives. Also includes volumes normally excluded, such as '\\?\Volume*' volumes. .PARAMETER WhatIf Shows what would happen if the command were to run. No actions are actually performed. .PARAMETER Confirm Prompts you for confirmation before executing any changing operations within the command. .NOTES Tags: Storage 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 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.
