[Sheepdog] general question about sheepdog operation (block distribution)

[Miles Fidelman]

Something that's not quite obvious from the documentation:

How does Sheepdog spread blocks around when nodes have multiple disks?  
For example, on a 4-node cluster, where each node has 4 drives, is 
Sheepdog smart enough to replicate blocks in ways that protect against 
both individual drive failures, and node failures that take out 4 drives 
at a time?

Thanks,

Miles Fidelman
