Question
Shared storage between Ubuntu servers
What process or program do you recommend for storing files on a shared folder between multiple servers? I have multiple Ubuntu servers that need to see the same file structure in real-time. Copying items to Amazon S3 is not an option. The servers are able to “talk” to each other across the private network. My thought is to make a dedicated droplet for just file storage and then symlink the other servers to the shared folder. Your advice is appreciated.

One person recommended NFS. I found this tutorial: https://help.ubuntu.com/community/SettingUpNFSHowTo
Any other recommendations?
glusterfs

If you don’t use redundancy, then you have the danger of single point of failure if any one of the shared servers go down.
