I'm putting together a horizontally scaled Apache/GluserFS setup. I'm trying to figure out how Gluster deals with permissions. I'm going to have several hosts reading and writing to the Gluster File System. I understand the basics of Linux file system permissions (ugo/rwe). I want to give one user (actually one user per host) certain file system permissions.
Basically, I want to give the www-data user (and only the www-data) on each host read/write permissions on the GlusterFS backed web directory tree. Is this possible? Are Gluster file permission based on the name, or the user ID?
