[sheepdog-users] Node Recovery

A slight confusion on my part in terms of node recovery -

Using Sheepdog 0.8.3 on Ubuntu 16.04 with Corosync and a simple setup.

I have 2 KVM servers set up and 1 cluster.

I have 2 VDI's in the cluster both of 20gb.

Neither VDI is active in the 2 KVM servers (i.e.all virtual machines stopped).


If i reboot (normal shutdown) a server (say node 0) on restart it says "node 0 in recovery" - it than seems to be rebuilding the VDI's on node zero (some 40gb of I/O).  Each time I reboot, the same occurs.

This somewhat confuses me.  Both VDI disks are identical on each node, no updates/writes have occurred - surely Sheepdog should know nothing has change?

What if I expand  this out to a Terabyte of VDI's - taking a node down for maintenance will incur massive delay on restart.

Am I doing something wrong?
