My only issue is that I believe copyTemplateToPrimaryStorage fails if
the source datastore is not NfsTO, so I'm not sure if this change will
do anything, or where S3 copy is actually handled. se
copyTemplateToPrimaryStorage:
KVM:
if (!(imageStore instanceof NfsTO)) {
return new CopyCmdAnswer("unsupported protocol");
}
Xen (all logic wrapped in this if statement):
if ((srcStore instanceof NfsTO) && (srcData.getObjectType()
== DataObjectType.TEMPLATE)) {
VMware:
if (!(srcStore instanceof NfsTO)) {
return new CopyCmdAnswer("unsupported protocol");
}
This line of code has a history. In 4.2 it didn't work for S3, either.
It specifically only allowed NFS:
if ((srcData.getObjectType() == DataObjectType.TEMPLATE) &&
(srcDataStore instanceof NfsTO) && (destData.getDataStore().getRole()
== DataStoreRole.Primary)) {
Then for a short while it was changed during some refactoring Chris
and Edison were working on:
if ((srcData.getObjectType() == DataObjectType.TEMPLATE) &&
(destData.getObjectType() == DataObjectType.TEMPLATE &&
destData.getDataStore().getRole() == DataStoreRole.Primary)) {
That broke CLVM, so I changed it to:
if (srcData.getObjectType() == DataObjectType.TEMPLATE &&
srcData.getDataStore().getRole() == DataStoreRole.Image &&
destData.getDataStore().getRole() == DataStoreRole.Primary) {
