distributed filesystem over internet/VPN

On this forum was already posted similar question, but it was 4 years ago and didn't give me answers.

I have two groups of engineers that works in far locations connected via VPN. Physically, the connection is a DSL. Currently we have a linux server in one location that provide files over SMB/CIFS. Thus live of people in the second location is a nightmare.

I can change a lot on the server, but one thing must remain. Workstation need to access files using standard windows mechanisms (SMB/CIFS). No extra software (drivers, clients etc).

To solve it, I want to install second server in the second location and use a distributed filessystem that mainly works in replication mode. Files on both servers will be redistributed by samba in the local network.

There is a great list of distributed filesystems on wikipedia.

The most advanced seams to be lustre. But I have some doubts if it will work for me. Lustre is dedicated to a true cluster with a high speed connection (10GigE or special hardware like RDMA). It also stripe space from all nodes, while I rather want to have replication/mirroring.

XtreemFS seams to be more adequate to me. At least from functional site. But it seams that it is JAVA based solution... I'm very afraid for the performance. There is also some limitation for read/write replication.

GlusterFS: according to some blog this filesystem is not good choice for high-latency connection like DSL. (sorry, forum disallow me to publish valid link, add http prefix: joejulian.name/blog/glusterfs-replication-dos-and-donts/)

What is your recommendation?
Had anyone similar problem?

QUOT(8) 						      System Manager's Manual							   QUOT(8)

NAME

       quot - summarize filesystem ownership

SYNOPSIS

       quot [ -acfguvi ] [ filesystem... ]

DESCRIPTION

       quot displays the number of kilobytes in the named filesystem currently owned by each user or group. Note that this utility currently works
       only for XFS.

OPTIONS

       -a     Generate a report for all mounted filesystems giving the number of kilobytes used by each user or group.

       -c     Display three columns giving file size in kilobytes, number of files of that size, and cumulative total of kilobytes in that size or
	      smaller file.  The last row is used as an overflow bucket and is the total of all files greater than 500 kilobytes.

       -f     Display count of kilobytes and number of files owned by each user or group.

       -g     Report on groups.

       -u     Report on users (the default).

       -v     Display three columns containing the number of kilobytes not accessed in the last 30, 60, and 90 days.

       -i     Ignore mountpoints mounted by automounter.

       -T     Avoid truncation of user names longer than 8 characters.

       -q     Do not sort the output.

FILES

       /etc/mtab	   mounted filesystem table
       /etc/passwd	   default set of users
       /etc/group	   default set of groups

SEE ALSO

       du(1), ls(1).

BUGS

       Currently, only the XFS filesystem type is supported.
