How do I unmount a tmpfs that is missing from /etc/mtab?
- by vrinek
I have the following line in /etc/fstab:
none /home/hydra/tmp tmpfs user,noauto,size=1000M,uid=1001,gid=1001 0 0
I can do mount ~/tmp as user hydra and it gets mounted ok. The only problem is that even thought it gets added to /proc/mounts, it does not get added to /etc/mtab. When I try a umount ~/tmp (again as hydra) it complains:
umount: /home/hydra/tmp is not mounted (according to mtab)
And when I try -f or -n, it complains that I am not root.
Some more info on the system that manifests this problem:
On sudo umount /home/hydra/tmp, the fs gets unmounted (I think I needed to used -f too)
Debian version is testing
mount --version - mount from util-linux 2.19.1 (with libblkid and selinux support)
ls -l /etc/mtab - -rw-r--r-- 1 root root 921 Nov 14 09:08 /etc/mtab
cat /proc/mounts | grep rootfs - rootfs / rootfs rw 0 0
/home, /home/hydra nor /home/hydra/tmp are symbolic links
