[sheepdog-users] .stale dir, error message after creating a vdi

[Valerio Pachera]

Description:

cluster with 4 nodes, each with 2 disks.

Clean start: all metadata and .stale dir removed before formatting the cluster.

What's wrong: after creating a vdi, in sheep I see an error message
about stale dir on the node were I run 'dog vdi create'.

(node test006)

But stale dir was already created by dog cluster format.

The same error message is present on node test007 but not on node
test004 and test005.
