SavageAUS Posted May 25, 2021 Share Posted May 25, 2021 So after many days moving my files around I’ve freed up 2 drives that have no shares or files on them but unraid is reporting 14Gb used and 6.67 on 2 empty drives. Both drives are 2tb wd reds. Sent from my iPhone using Tapatalk Quote Link to comment
itimpi Posted May 25, 2021 Share Posted May 25, 2021 Sounds about right. Even a drive with no files on it will have space used to hold the file system structure information, with the amount used varying by file system type. Surprised the values are not the same if the disks are the same size and using the same file system. Having said that the more recent versions of XFS have a larger overhead when creating an empty file system so maybe that explains the difference? Quote Link to comment

What would be the safest approach to “wipe” the drives so that the used space is the same?Because the drive is empty can I stop the array, un assign it, format it xfs then put it back in the array? Will this trigger a rebuild?Both drives are already xfs. Sent from my iPhone using Tapatalk Quote Link to comment

If you want to reformat the drives the procedure is covered here in the online documentation that can be accessed via the Manual link at the bottom of the Unraid GUI. Quote Link to comment
