Fine-grained permissions in distributed filesystems Lustre, GlusterFS, AFS and others
 

What other distributed file systems, as scalable as AFS, have more fine-grained access control than rwx and what are they?

AFS (Andrew File System) ignores the old rwx file permissions and allows more fine grained rlidwka. That stands for read, lookup, insert, delete, write, lock, and set ACLs. What do Luster and GlusterFS use and are they comparable to AFS?
