Subject: sshfs in combination with bind mounts and umount -f fails Package: sshfs Version: 2.2-1 Severity: normal
*** Please type your report below this line *** If an sshfs file system is mounted, then mapped to a different location in the file system using a bind mount and then the bind mount is unmounted using the -f (force) flag (as is done for example in /etc/init.d/umountfs), the sshfs mount breaks: --- root:~/.ssh# mkdir -p /mnt/mp1 root:~/.ssh# mkdir -p /mnt/mp2 root:~/.ssh# sshfs localhost:/home /mnt/mp1 root:~/.ssh# mount -o bind /mnt/mp1 /mnt/mp2 root:~/.ssh# umount -f /mnt/mp2 root:~/.ssh# ls /mnt/mp1 ls: cannot access /mnt/mp1: Transport endpoint is not connected --- This is a problem when the bind mount is within a container (OpenVZ, lxc) and the container runs unmodified init scripts that unmount the bind mount with the -f flag. It leads to all other applications and containers to not be able to read from the sshfs mount any more. The problem also occurs with glusterfs, the it may be a problem in the fuse libraries or kernel driver. -- System Information: Debian Release: 6.0 APT prefers squeeze-updates APT policy: (500, 'squeeze-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.32-5-amd64 (SMP w/1 CPU core) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages sshfs depends on: ii fuse-utils 2.8.4-1.1 Filesystem in USErspace (utilities ii libc6 2.11.2-10 Embedded GNU C Library: Shared lib ii libfuse2 2.8.4-1.1 Filesystem in USErspace library ii libglib2.0-0 2.24.2-1 The GLib library of C routines ii openssh-client 1:5.5p1-6 secure shell (SSH) client, for sec sshfs recommends no packages. sshfs suggests no packages. -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
