Enable xattr for dumb filesystems
#################################

:tags: xattr,filesystems,davfs
I was looking for a way to enable extended attributes for encfs(userland
crypto Wrapper) on davfs(userland Webdav fs wrapper) to use them with
glusterfs to create a high-availability distributed secure cloud storage
on the cheap.
After many hours looking for a way to enable xattrs on encfs or ecryptfs
and davfs or wdfs i found pyfilesystems to write and mount an xattr
wrapper for the retard fs.
install pyfilesystem and encfs davfs
====================================
.. code-block:: bash
pip install fs
apt-get install davfs2 encfs
mount davfs and encfs
=====================
.. code-block:: bash
#?/bin/sh
echo "https://path/to/webdav username password" >> /etc/davfs2/secrets
mkdir /mnt/{1,2,3}
mkdir /mnt/1/.encfs
mount.davfs https://path/to/webdav /mnt/1
encfs /mnt/1/.encfs /mnt/2
mount wrapper fs
================
.. code-block:: python
#?/usr/bin/python
from fs.osfs import OSFS
from fs.xattrs import SimulateXAttr
stupid_fs = OSFS("/mnt/2")
xattr_fs = SimulateXAttr(stupid_fs)
fuse.mount(xattr_fs,"/mnt/3")
Now /mnt/3 can be used as a brick in glusterfs. Or just use tahoe-lafs ;P
