In Ubuntu 14.04 systems I would like to store the same contents of a directory in two physical different devices (1). This is to let the same person work on different workstations on the same LAN, having the same files available at any time, regardless of the workstation he decided to work with: they can be text files, configuration files, but also pdf and so on. (2)

Both the workstations can use sshfs, but not NFS. I need real-time (so no rsync), bi-directional (so no lsyncd) syncronization between the two directories.

Does exist a tool, or filesystem, which is able to perform this?

(1) I don't need neither symbolic links, nor mount --bind, because the contents should be stored in different devices and none of those solutions would allow this.

(2) This is the main scenario. A unique USB key can be used, but often the number of files and their total dimensions are huge, so they would require a hard disk.

(1) This is also to make a backup: if one workstation is down, the other already has all the files. I don't need neither symbolic links, nor mount --bind, because the contents should be stored in different devices.

In a Ubuntu 14.04 system I would like to store the same contents of a directory in two physical different devices. This should result in having in the filesystem tree two directories dirA and dirB with the same contents. I would like to work on them, keeping them synced. Any modifications made in dirB should be mirrored in dirA and viceversa.

I did not choose rsync because I need a real-time syncronization to be set once; lsyncd works well in (almost) real-time, but it has some issues when trying to use it bidirectionally. I don't need neither symbolic links, nor mount --bind, because the contents should be stored in different devices and none of those solutions would allow this.

There should not be a client and a server: the actions performed against dirA should be replicated at the same time in dirB and viceversa.

• Does exist a tool, or filesystem, which is able to perform this?

• Does such a tool/filesystem exist when dirB is in another machine?
