[sheepdog-users] cache flush: all or nothing

[Valerio Pachera]

Last thing I  tired is to remove the node 'sheepdog004' and insert it
backup right agfter, hoping ti was going to "refresh" its vdi list,
but it didn't change.

At this point the only thing left to do is to remove 'sheepdog004'
form the cluster and cleat its data.

Any better idea?

PS:
guest continue to complain about
  status: DRDY
  failed command: FLUSH CACHE EXT
and it fails to halt.
