[jira] [Updated] (CLOUDSTACK-6462) Migration of CLVM volumes to
another primary storage fail
[ https://issues.apache.org/jira/browse/CLOUDSTACK-6462?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Salvatore Sciacco updated CLOUDSTACK-6462:
------------------------------------------
Description:
ACS version: 4.2.1
Hypervisors: KVM
Storage pool type: CLVM
Since we upgraded from 4.1 to 4.2.1 moving volumes to a different primary storage pool fail. I've enabled debug on the agents side and I think there is a problem with the format type conversion
Volume on database had format QCOW2
these are the parameters for the first step (CLVM -> NFS):
