hi,Hitoshi
we've tested the patch. Our test method is:
We attached a 20G sheepdog VDI to a VM holded by openstack. And we created
a 2G file which we have it's md5 in hand in the VDI.
We killed the non-gateway nodes in the middle of the process, then
restarted the cluster. The process resumed
Epoch won't increase if there are only gateway nodes in the cluster.
In this way, when the cluster restarts, it will always recovery from a
latest epoch version which has at least one non-gateway node in the cluster.
This patch fixes bug data wipe bug in the recovery described here:
