Can't access folders mounted by sshfs after sleep

Question

Often, when I mount a filesystem via ssh:

sshfs user@remote: ~/Mounts/Remote

and the machine hibernate (closing the Laptop lid) if I wake up the machine I can access the mounted folder. Furthermore, if I try to ls in the parrent folder, the terminal freeze. If try to unmount using

fusermount -u ~/Mounts/Remote

I can't do this becouse:

fusermount: failed to unmount /home/yotama9/Mounts/Remote: Device or resource busy

I tried to kill ssh but I can't mount the folder again. ls in the folder still freeze.

How can I avoid this and fix this (Arch Linux)?

Answer 1

I suffer the same problem in Ubuntu Linux. What I do after resume:

$ killall sshfs

Then, umount and mount again the remote filesystem.
