"Operation not supported" using EncFS over WebDAV gvfs-mount

["R. Diez" <rdiezmail-temp2 yahoo de>]

Hi all:

I am trying to ask the following question in 
encfs-users lists sourceforge net , but as the message is not getting 
through, I thought I might also ask here, in case someone can help in 
the meantime:

I am trying to use EncFS over WebDAV, as it is relatively easy to find 
free virtual disk ('cloud' drive) providers on the Internet that support 
WebDAV. You normally have to pay for other protocols, like SSH. I want 
my files to be encrypted, so that the provider and/or NSA cannot spy on 
my data.

I am using Kubuntu 14.04.4. The script I am developing to that purpose 
is here:

https://github.com/rdiez/Tools/blob/master/MountStrato/mount-strato.sh

I got EncFS to work over a davfs2 mount. However, using 2 stacked FUSE 
filesystems leads to frozen kernel threads, see the comments in the 
script above more more details. So I am trying to mount the WebDAV drive 
with gvfs-mount now.

However, the gvfs-mount method only works partially. I can read files 
and create directories, but other operations, like copying a file with 
'cp', fail:

cp: cannot create regular file 
‘/home/rdiez/StratoHidrive/MountpointEncrypted1/Test/mount-strato.sh’: 
Operation not supported

I have already invested quite a lot of time for this seemingly easy 
task. Before I dig further, I wanted to know if this problem is already 
known. If not, what would be the easiest way to find out what operation 
failed? i heard that no all file operations are supported over WebDAV / 
gvfs-mount.


Please copy me on any e-mails, as I am not subscribed to this list.

Thanks,
