It works here with sshfs-fuse-2.4. Maybe it is because the directory
lives directly under /? Try mounting it in a directory inside $HOME,
and see if it works that way.

Hi,

Since two days I think, I have the same problem. Not with sshfs, but
with NTFS-3G, which uses FUSE. I can mount as user, but I can only
unmount as root.


I've no idea what package is responsible for this change of behavior.

It appears to be the kernel module AFACT. I tried every version of fuse
going back to 2.8.6, all with the same problem. Then I tried it on a box
still running a 3.9.6 kernel and it worked as it should.

This can't be it. I didn't update the kernel. But I booted an older
kernel anyway to test (3.5.2) and the problem was still there.


Something else changed.

3.5.2 isn't that much older, when did this stop working for you? I
haven't used sshfs in a while, I've no idea when it broke here. BTW that
should read 3.0.6 for the older kernel I tried it on.

About 3 days ago. Maybe 4.

It works here with sshfs-fuse-2.4. Maybe it is because the directory
lives directly under /? Try mounting it in a directory inside $HOME,
and see if it works that way.



Unfortunately, this doesn't work either.
It seems to be related to a recent kernel as others have similar
problems with fuse reported elsewhere.


Thanks,
Helmut.

I filed a bug now:

Everyone who's affected should feel free to confirm there.

Happens here, too, with mp3fs. I'm not able to login to Gentoo
Bugzilla now but will add my vote later if I get a chance.

Doing, e.g.,

sshfs -o transform_symlinks -o Cipher="blowfish" numa-sv:/Save /numa-sv

works just fine.

[...]

BUT trying to do (which has been working for a long time)

fusermount -u /numa-sv

now gives

fusermount: entry for /numa-sv not found in /etc/mtab


OK, the culprit was util-linux-2.22. If you want a fix right now, the
upstream patch that fixed the issue is:


http://git.kernel.org/?p=utils/util-linux/util-linux.git;a=patch;h=4be900c51d371a7a41495e4eca2d29 fc77c20c7c
