[jira] [Commented] (CLOUDSTACK-4551) Migrating the data volume from
NFS to local storage ,underlying disk offering is not changed.
[ https://issues.apache.org/jira/browse/CLOUDSTACK-4551?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13797647#comment-13797647 ]
Koushik Das commented on CLOUDSTACK-4551:
-----------------------------------------
This shouldn't be allowed. Even though the volume may get migrated from shared to local storage, it is not possible to update the disk offering. So the fix is to disallow migration.
