Our setup:
cluster.shd-max-threads: 2
cluster.shd-wait-qlength: 10000

Well, maybe our setup with 3 servers and 4 disks=bricks == 12 bricks,
resulting in a distributed-replicate volume (all /dev/sd{a,b,c,d}
identical) , isn't optimal? And it would be better to create a
replicate 3 volume with only 1 (big) brick per server (with 4 disks:
either a logical volume or sw/hw raid)?

But it would be interesting to know if a replicate volume is healing
faster than a distributed-replicate volume - even if there was only 1
faulty brick.
