[Gluster-users] rsync to gluster mount: self-heal and bad performance

[Tiemen Ruiten]

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:
