Dear Ben Ali,
thanks for your answer, yes, I can manage the VMs under the cluster? In this
plastform, which have one zone, one pod, and two cluser, three hosts. I test
the snapshop create command in different cluser, the result is same.
from the UI and management log, I think all clusters and hosts were UP
state, and I can upload template, create new VM, migrate VM, but when I create
snapshot from volume, I get this error, it seems tell me the snapshot created
successfully, but can't backup to secondary storage. I don't know the reason.
Best,changhua

snapshot failed
Hey,
in fact your primary storage is inaccesible,
You can start by verifiying the status of the cluster and his hosts.
Are you able to manage the VMs under the cluster ?
Regards.
