To help track disk space on a cluster, here’s a simple batch script that works on Windows. It accepts a list of hostnames, and outputs the size and free space on each server to a log file.
The script is available on GitHub; the version at time of writing is here:
@echo off :: Batch file to log out a local drive report to a .log file in the same directory :: Log files are named based on the date and time :: Specify which servers to attempt to return disk space for (delimit with spaces) :: Enter hostname, and ensure the account running this script has local or domain admin rights set SERVER_LIST=server :: Set output date time (YYYYMMDD_hhmmss) set LOG_TIMESTAMP=%date:~-4,4%%date:~-7,2%%date:~0,2%_%time:~0,2%%time:~3,2%%time:~6,2% set LOG_DATE=%date:~-4,4%%date:~-7,2%%date:~0,2% set LOG_TIME=%time:~0,2%%time:~3,2%%time:~6,2% :: Specify output prefix - this uses an absolute path, if you prefer to use relative then ensure the scheduler includes a "start in" path set LOG_LOCATION=C:\DriveReport\DriveReport_%LOG_TIMESTAMP%.log :: Create empty output file >nul copy nul %LOG_LOCATION% :: Loop over each server to return stats and append to log file echo ServerName,LogDate,LogTime,Drive,Size,FreeSpace>>%LOG_LOCATION% for %%i in (%SERVER_LIST%) do ( for /f "tokens=1,2,3" %%a in ('wmic /node:"%%i" LogicalDisk Where DriveType^="3" Get DeviceID^,Size^,FreeSpace^|find ":"') do @echo %%i,%LOG_DATE%,%LOG_TIME%,%%a,%%c,%%b>>%LOG_LOCATION% )
This outputs one log file per run, containing a row per drive.
This can be scheduled using Windows Task Scheduler and has been tested on Windows 10, Windows Server 2012R2, Windows Server 2016.
