Subject RE: VM & Storage migration only works once & not vice versa CS 4.3 Xen 6.2 SP1
Date Mon, 25 Aug 2014 04:30:40 GMT
Hi Amin,

There are no error messages in the log snippet you have provided. 
Is the host in the 2nd cluster from which you are trying vm& storage migration (2nd time
after successful migration) able to mount the primary storage in the cluster1? If not you
may have to resolve that issue. Otherwise open a defect.

Thanks,
Sanjeev

Subject: VM & Storage migration only works once & not vice versa CS 4.3 Xen 6.2 SP1

Hello,

 
We have two clusters, the environment is as follows:

?         CS Mgmt server 4.3 on CentOS 6.5

?         Hypervisors Xen Server 6.2 SP1.

?         One Zone, Two clusters with different two primary storage servers.

?         Primary & Secondary storage are NFS based.

 
When attempting to move a VM from one cluster to another, we succeed only the first time,
the VM and its files are moved to a new hypervisor and new storage server in the new cluster,
however when attempting to migrate the VM to the original cluster, host, and original storage,
the migration fails, so it is only one time migration.

 
The logs are as follows, we would appreciate if someone has faced this issue before, it is
very helpful feature in cloud stack to migrate across clusters and storage servers, but it
seems it is not working, cause we simulated the environment on CS 4.3 from scratch installation
and the behaviour is the same.

 
/mnt/DATA/VM-SEC-01/volumes/2/1071 is not being created.
