[Gluster-users] disperse volume brick counts limits in RHES

[Serkan Çoban]

Healing gets slower as you increase m in m+n configuration.
We are using 16+4 configuration without any problems other then heal speed.
I tested heal speed with 8+2 and 16+4 on 3.9.0 and see that heals on
8+2 is faster by 2x.
