Attach Block Storage Volumes to Multiple Droplets

Great thing you've done with block storage, most impressive and very useful. In the future if one block storage volume could be seen and used by multiple Droplets, it would make life sooooo much better and easier, to share install files, user files, possible backup images and much more between droplets. Great work DigitalOceanTeam!

Indispensable feature for HA architectures

This would be handy when you have many droplets accessing the same files. Especially when your doing batch processing.

I think if we could be guaranteed by DO that using Spaces for this would have the same performance as Block Storage. Then people could just use Spaces. But not sure if thats possible.

read-only attachment should be available. provide an option for read/write access on attachment phase

This would be useful in the context of Kubernetes too, where multiple pods can use a shared volume.

Thanks for the suggestion. This was a very common request during our beta, we are considering how we can accommodate that request but we don't have any specific plans to share so far.

This would be a great feature and would cut out the need to setup replicated file systems such as glusterFS on each droplet.

That wouldn't be block storage anymore. You can't connect a single hard disk to two PCs, can you?

As Nicolás said, I don't think you realise what you're asking for. Even if DO offered this, you can't just put a standard filesystem on a shared storage and expect the files to be available from multiple locations - you need specialised filesystems and distributed locking managers, an ext3 of xfs filesystem would corrupt in minutes as soon as writes from the second location started, or as soon as the second mount started a journal replay.

I think you want NFS https://en.wikipedia.org/wiki/NFS or something along those lines. I agree with others that this would be outside the scope of volumes.

Might be a nice separate type of resource, or perhaps to have NFS one-click-apps where nodes could auto-join.

Can't we just mount the block storage on the other droplets ?
