I have some software which unmounting folder during it's operation. But for some reason it can't do it. When I trying to umount folder manually (almost in same time) it does work. Can someone let me know if atop utility can track process usage for some folder? As I can't see any process using exact file with lsof/fuser/ps.

  • I do not know if atop can do such a thing but, probably, you missed -m option of fuser. Try fuser -m MOUNTPOINT. – andcoz Jan 30 '17 at 10:39
  • no, I used fuser -vm. No data. – user3417815 Jan 30 '17 at 10:49
