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:
