-------------------------------------------
Summary: Unable to convert to json in Storage XenMotion
Key: CLOUDSTACK-9081
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9081
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Reporter: Rajani Karuturi
Storage motion of vm across clusters/xenserver-pools fails
in a clustered management server setup. In xen storage motion we have to send a
migrate_receive command to the destination host, followed by migrate_send
command to the source host. The sr and network detials of the destination host
have to be passed in migrate_send command on the source. While migrating across
clusters the source and destination resources are seperate objects. To pass
this information across resources we have to send seperate migrate with storage
receive and send commands to the resource. In a clustered ms setup these
commands may have to be forwarded to another ms as the resource may be owned by
it. The serilization of the command and answer objects fails in such case as it
doesn't understand the xapi sr and network objects.
The following JSON conversion error was recorded in management-server2.log.
