Description

We used MN.updateSystemMetadata to add those policy to the object tao13350.1:

urn:node:mnDemo5
urn:node:mnDemo8

We can see the policy was added to both MN and CN:
https://mn-demo-6.test.dataone.org/knb/d1/mn/v2/meta/tao.13350.1
https://cn-dev-ucsb-1.test.dataone.org/cn/v2/meta/tao.13350.1

But we got the NotFound on demo-5/8
https://mn-demo-8.test.dataone.org/knb/d1/mn/v1/meta/tao.13350.1
https://mn-demo-5.test.dataone.org/knb/d1/mn/v1/meta/tao.13350.1

Note: in the systemMetadata of cn, we can't see the replica part.

fixes #7314: systemMetadata updates were overwriting the replica sections of the CN systemMetadata. Refactored so that existing replica information from the CN is copied, and replica section of systemMetadata created if it's not there. Updated occurrences of TypeMarshaller.convert... to TypeFactory.convert (due to refactored d1_common_java)

Revision 16243
Added by Rob Nahf about 9 years ago

refs: #7314, #7324: Removed restriction on dateSystemMetadtataModified field that was preventing update of an object. Added logic for rejecting updates if the CN is authoritative for the systemMetadata (v1 read-write nodes). Added missing business-rule validation on systemMetadata.

the V2TransferObjectTask.processUpdates code neglected to preserve the existing replica information the CN held. Fixed it so it does, and restores replicas if the CN doesn't have a replica section in it's copy of the systemMetadata.

Need to redeploy d1_synchronization to DEV, then try updating the object's systemMetadata again from the authoritativeMN. It should kick off replication for that object.

Hi Rob, I deployed the cns on cn-dev-1 yesterday. However, the replica sections on the system metadata still doesn't show up:
https://cn-dev-ucsb-1.test.dataone.org/cn/v2/meta/tao.13350.1

And mn-demo-5/8 don't have the replica:
https://mn-demo-8.test.dataone.org/knb/d1/mn/v2/meta/tao.13350.1
https://mn-demo-8.test.dataone.org/knb/d1/mn/v2/meta/tao.13350.1

#7 Updated by Jing Tao about 9 years ago

Weird, I just inserted a new object and I can see the replica part:
https://cn-dev-unm-1.test.dataone.org/cn/v2/meta/tao.13359.1

However, for an object which was inserted a week ago, I still can see the replica part:
https://cn-dev-unm-1.test.dataone.org/cn/v2/meta/tao.13350.1

#8 Updated by Jing Tao about 9 years ago

After more than one hour when I updated the system metadata by adding the replication policy, the replication policy still has been fulfilled.

#9 Updated by Jing Tao about 9 years ago

For the object which I uploaded couple weeks ago, the replication policy hasn't been fulfilled:
https://cn-dev-ucsb-1.test.dataone.org/cn/v2/meta/tao.13350.1

For a object which I uploaded this morning, the sync hasn't happened:

https://mn-demo-6.test.dataone.org/knb/d1/mn/v2/meta/tao.13361.1
https://cn-dev-ucsb-1.test.dataone.org/cn/v1/meta/tao.13361.1
