[sshfs] *** urgent *** fusermount -u gives : entry for /numa-sv not found in /etc/mtab

[Helmut J. <jar...@ig...>]

Hi,

please excuse the "*** urgent ***" tag, but I'm using sshfs in my daily  
backup
which is broken now.

Since a short time I have a critical problem with sshfs.
I cannot unmount it !

Doing, e.g.,

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

works just fine.

df shows
numa-sv:/Save  148976776 102070872  40882408  72% /numa-sv

grep /numa-sv /etc/mtab  shows

numa-sv:/Save /numa-sv fuse.sshfs rw,nosuid,nodev 0 0


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


I'm using  (GenToo version numbers)

kernel 3.5.3

openssh  6.1_p1

sshfs-fuse  (GIT version 2012/09/13)

fuse  2.9.1-r1

I can't use  fuse from GIT since it break many packages on my machine.

Many thanks for a hint,
Helmut.
