[Gluster-users] how to accelerate the self-heal process?

I have a replication volume as bellows:

[root at gluster001 disk]# gluster volume info rep

Volume Name: rep

Type: Replicate

Volume ID: 0f7eb8a0-92d7-4911-b766-f23ed870cf3d

Status: Started

Number of Bricks: 1 x 2 = 2

Transport-type: tcp


Brick1: gluster001:/disk/sdc

Brick2: gluster002:/disk/sdb

The sdc and sdb are both raid5 device in 3 SAS disks.

And I have 3 clients
(gluster-client001,gluster-client002,gluster-client003) mount on the same
replication volume.To test the self-heal function, I clean
gluster001:/disk/sdc (rm ¨Crf /disk/sdc/*), and run ¡°gluster volume heal rep
full¡±. I use the iftop to check the process and I get the log :

 [image: ÄÚǶͼƬ 2]The clients are, and
There are no jobs running on the clients. But from the log, the client 4.17
and 4.19 are reading something from the gluster002 server. And the
self-heal process¡¯s performance seems to be affected, only 253Mb/s.

My Questions, thanks:

@1: why/what are the clients 4.17 and 4.19 reading from gluster002?
@2: how to accelerate the self-heal?
