The usecase [of glusterfs] was sharing thumbnail cache between multiple ec2 machines in the same az, serving an e-commerce site, before efs was a thing.

The performance of the site tanked really badly due to how long io and discovery took on files in glusterfs, way beyond of what was acceptable.

The cross site (resd eu->us) gluster sync was also a pile of dirt, failing with obscure errors and getting stuck quite often.

This is just first hand experiences and I don’t want to touch it ever again.
