[sheepdog-users] Snapshot and Cache stress test

[Valerio Pachera]

I've been trying with qemu cache=directsync.
Sheepdog daemon version 0.7.0.

The first run it didn't crash.

The second run I got

  Aug 20 11:06:15  ERROR [main] gateway_op_done(119) leaving sheepdog cluster.

I noticed a node has a slightly different date/time of 18 seconds.
I'm going to fix that and repeat the test.

Here's the vid list.
Notice there are several id 0!
