Hello Oritwas,
I am aware of that you are responsible for the issue 17111
(http://tracker.ceph.com/issues/17111).
Actually, I proposed two fixes already. Could you please take a look at
them?
1.
https://github.com/ceph/ceph/pull/10820/commits/2e95e2c824c6cc829c39180b0f6809ff312e5892
In this proposal, I added two items into manifest :
src_instance
copied_object
"copied_object" is used to indicate whether this object is generated
through COPY operation.
If so, we must overwrite "instance" with "src_instance" in the GET
operation.
If not, go as before.
We don't need extra tools to fix the old object's manifest that created
before this patch, because
copied_object's default value is false.
2.
https://github.com/ceph/ceph/pull/10820/commits/5104f852d255cfc140be33885f696b7f93a6cfad
This is an optimized version. Only src_instance is added to manifest.
In order to distinguish object generated through COPY operation from
object generated through
PUT operation, I make the none copied object's src_instance equal to its
instance value.
So if src_instance not equal to its instance, this is a copied object.
However, this proposal need an extra tool to migrate old objects to new
version RGW with this patch.
Your comments are highly appreciated!
thx,
Yang Honggang
