Subject 转发:cs4.0.2 snapshot failed
Date Mon, 29 Dec 2014 00:06:29 GMT
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

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.
