Hi Tiemen
It sounds like you're trying to rsync files onto your Gluster server,
rather than to the Gluster filesystem. You want to copy these files into
the mounted filesystem (typically on some other system than the Gluster
servers), because Gluster is designed to handle it that way.
I can't remember the nitty gritty details about why this is, but I've
made this mistake before as well. Hope that helps. :)

Hello,
While rsyncing to a directory mounted through glusterfs fuse,
performance is very bad and it appears every synced file generates a
(metadata) self-heal.
The volume is mounted with option acl and acl's are set on a
subdirectory.
Setup is as follows:
Two Centos 7 VM's (KVM), with Gluster 3.7.6 and one physical CentOS 6
node, also Gluster 3.7.6. Physical node functions as arbiter. So it's
a replica 3 arbiter 1 volume. The bricks are LVM's with XFS
filesystem.
While I don't think I should expect top performance for rsync on
Gluster, I wouldn't expect every file synced to trigger a self-heal.
Anything I can do to improve this? Should I file a bug?
Another thing that looks related, I see a lot of these messages,
especially when doing IO:
