I think I found the solution using self-healing. Before that I need to make an image of the running node as the recovery image to save the self-healing time.
Do you guys have other ideas about it?

But the problem is that it has no data, will the GlusterFS find the data inconsistency and replicate from another brick to the new recovered brick? Or should I run fschk to trigger the data fixing?
