Hi,

On a site, I have an oVirt setup made of 3 nodes acting as 
compute+storage based on gluster, plus another standalone engine.
The replica-3 seems to do some good job even when I test-stressed them 
brutaly.
But as I have the opportunity to add more storage nodes, I'm interested 
in the comment above.

When adding another node, what is the effect on the duration of a 
rebuild when recovering from a crash? What is the effect on perfs?

Regards,
