Created bucket class with spread policy in test cluster. Provisioned obc and added some data. Modified placement policy to replica. The data got replicaed to new backingtore, however, bucketclass is stuck in configuring phase with syntax invalid error. Can't create new obc from it.

To verify syntax and spec of edited bucket class, created one more bucket class from GUI with mirror policy. It was created successfully. The spec section of both bucketclasses is same.
Not sure why noobaa-operator is throwing invalid syntax message.

---------------

TEST 1:

1. Created a backingstore

~~~
test-bs-1                      pv-pool         Ready   10m
~~~

2. Created a bucket class with spread placement policy

~~~
test-bucket-class             {"tiers":[{"backingStores":["test-bs-1"],"placement":"Spread"}]}                             Ready   0s
~~~

3. Created an obc and put some data

~~~
oc get obc|grep test-sona

5. Changed placement policy to mirror in bucketclass

oc get bucketclass test-bucket-class -o yaml
~~~
spec:
  placementPolicy:

    message: 'Failed to update bucket class "test-bucket-class" with error: error:
      invalid input syntax for type json - Can''t revert changes'
    reason: TemporaryError
    status: "False"
    type: Available
~~~

In noobaa-operator logs, observed "invalid input syntax" message:

~~~

~~~

6. The data got replicated in new backingstore.

7. Created a obc. It got stuck in pending state:

~~~
oc get obc|grep test-sona-2

test-sona-2   openshift-storage.noobaa.io   Pending   12m
~~~

obc is stuck in pending state as bucketclass is not ready:
~~~
  Warning  BucketClassNotReady  2m37s (x17 over 13m)  noobaa-operator  BucketClass "test-bucket-class" is not ready
~~~

--------

TEST 2:

1. Created a new bucketclass from GUI. 

~~~
oc get bucketclass|grep replica

replica-bucket-class          {"tiers":[{"backingStores":["test-bs-3","test-bs-4"],"placement":"Mirror"}]}                             Ready         22m
~~~

2. The bucketclass is provisioned successfully. The syntax of spec section is exaclty same as that of the older bucketclass which was modified:
~~~
oc get bucketclass  replica-bucket-class -o yaml
apiVersion: noobaa.io/v1alpha1
kind: BucketClass
[..]
spec:
  placementPolicy:
    tiers:
    - backingStores:
      - test-bs-3
      - test-bs-4
      placement: Mirror
[..]      
  phase: Ready
~~~

Moving the bug to 4.14.8 as we had had exceeded the fixes to be taken in 4.14.7.

Please sync with Bipin, this is a customer case

Hi Danny,

Customer upgraded ODF to fixed version (4.15.2).

The bucketclass is still stuck in configuring phase.

It is stuck at the mirroring quay bucket as tiers in quay-datastore-62864698-3ac5-4ae1-bae1-c87271963ec2 already exists on both backing stores.

How can we proceed here? Is there any way to skip mirroring the tiers which are already mirrored?

Hi Danny,

Did you get a chance to check this?

Hello Danny,

Can we continue on this bug for troubleshooting the issue as bug was primarily opened for this case.


1. Created a bucket for Quay to use with the default bucket class. (non-replicated)
2. Modified the bucket class to enable mirroring the data to AWS S3. At this time, everything was working fine and the bucket class state was not Configuring. The bucket class configuration was then stored in Git so it can be monitored by OpenShift GitOps
3. After some time, the bucket class went into Configuring state and never went out again.

Backingstore

~~~

After upgrading to ODF 4.15.2 the issue persists. Bucket class is still in configuring phase:

noobaa-default-bucket-class   {"tiers":[{"placement":"Mirror","backingStores":["noobaa-default-backing-store","aws-glacier"]}]}   null               null    Configuring   1y361d2h41m12s   

It is stuck at the mirroring quay bucket as tiers of bucket quay-datastore-62864698-3ac5-4ae1-bae1-c87271963ec2 already exists on both backing stores.
