Are There Reasonable Multi-Master Over the WAN Storage Options?

Hmm, I can't remember exactly but I think the BBC actually pulled this off with a particular product.
I can't remember what it's called.
You can do it, like I can build it with GFS2 and DRBD, the problem is once a WAN link fails you have a disaster. Do you simply cut everyone off? Or do you allow local edits?
No I mean actually sorting it despite that.
Done some googling to see if I can find the product but can't but effectively, the storage at each location is irrelevant, what you do is use a digital asset management system.
This does your versioning of media files, checking, quality control. It's a very different way of working to "everyone throw your data into a file browser"

I would think it depends on the system and how it actually checks if a file is being accessed. If the WAN link is down it would most likely assume that no one else has it opened or just error out if its configured to do that if unable to connect. I haven't had to do this though.

We do that with Sharepoint, but it doesn't support multi-master and it doesn't sort out conflicts.

That's the problem it either has to lock everyone out or allow conflicts.

But certain DAM packages do that. it's built specifically for digital assets which are constantly being edited/changed.

They are stored as the same file but can see the different versions, which user worked on which version, ect.

My multi-master system does that naturally. In both cases, humans have to sort it out later.

Man, I can see all kinds of problems with that system. and as Scott said, it has to be sorted by a person.

Yeah. All the workable solutions I've seen involve change tracking of some sort.

There are systems that do this with version control. You could do this with GIT or Mercurial, in theory. But eventually a human always has to sort things out.
