I have a lun and it occupies around 95% of used space. The lun is attached to windows server and I have done some housekeeping on the drive (consider G:\). now G: drive shows 60% of free space but lun still shows 95% of used space. please assist if it is any bug or how to rectify it.
Basically, you need Snapdrive to reclaim space from this LUN. DOT does not see the space left by the deleted files as free space because when you delete them via OS (Windows), DOT is not informed that it should free the associated blocks. You tell DOT to free those blocks via the space reclamation feature in Snapdrive.
