There you have it. "lsof" command should not output anything if examined object is not in use. I assume that "/dev/sdb1" gets auto-mounted by gvfsd [1] for user with UID 1001. AFAIK GIO and company implements different mounting scheme without involving traditional kernel mounting and allow to restrict mounted devices only for user who mounted them.Maybe something simple like "lsof" command can shed some light on this problem?$ sudo lsof /dev/sdb $ sudo lsof /dev/sdb1root@martha:~# lsof /dev/sdblsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1001/gvfsOutput information may be incomplete. root@martha:~# lsof /dev/sdb1lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1001/gvfsOutput information may be incomplete. root@martha:~#So even root user can't access them if they are mounted by other user. Try to use gio [2] utility to check status and unmount "/dev/sdb1" device. [1] man gvfsd [2] man gio
I man'ed them, but I got nothing useful for my trouble. How does one stop gvfsd, or tell it not to mount anything (right now). I'm about mid-grade with Linux skill, and the care and feeding of demons is a little above my pay grade.
root@martha:~# gio mount -u /dev/sdb1 gio: file:///dev/sdb1: Containing mount for file /dev/sdb1 not found root@martha:~# gio mount -e /dev/sdb1 gio: file:///dev/sdb1: Containing mount for file /dev/sdb1 not foundAny advice as to how to stop the auto-mounter, gvfsd, or fuse, etc. from tying up my disk, or how to get fsck to scan it?
