[sheepdog] [PATCH v1 0/5] using disks to generate vnodes instead of nodes

[Robin Dong]

From: Robin Dong <sanbai at taobao.com>

When a disk is fail in a sheepdog cluster, it will only moving data in one node
to recovery data at present. This progress is very slow if the corrupted disk is
very large (for example, 4T).

The solution to accelerate the speed of recovering is using disks to generate
vnodes so the failing of one disk will cause whole cluster to reweight and
moving data.
