Description of problem:
With fuse 2.8.3-3.el6_1, trying to unmount an sshfs mountpoint using 'fusermount -u /mnt/point' results in the error "fusermount: failed to unmount /mnt/point: Bad address:
Using fuse 2.8.3-1.el6 does not exhibit this behavior.
The current workaround is to either use umount or stay on 2.8.3-1.el6
Version-Release number of selected component (if applicable):
1. Mount sshfs:
# sshfs 10.12.53.162:/media /mnt/fuse/
# mount | grep fuse
10.12.53.162:/media on /mnt/fuse type fuse.sshfs (rw,nosuid,nodev,max_read=65536)
# fusermount -u /mnt/fuse/
fusermount: failed to unmount /mnt/fuse: Bad address
For the sshfs filesystem I'm using fuse-sshfs-2.2-1.el6.rf from rpmfusion.
