Fix Version/s: 2.1.0
Resolution: Fixed
> QUASI-CLOSED Container State Causes Checksum Mismatch After Replica
> Re-Replication
> ----------------------------------------------------------------------------------
>
> Key: HDDS-13491
> URL: https://issues.apache.org/jira/browse/HDDS-13491
> Project: Apache Ozone
> Issue Type: Bug
> Components: Ozone Datanode
> Reporter: Bablu Raul
> Priority: Major
> Fix For: 2.1.0
>
>
> To achieve the quasi-closed state, I stopped DataNodes 15, and 8
> {code:java}
> data8 0
> data16 976cd849 ← Original checksum
> data15 0 {code}
> After running the reconcile command, it correctly replicated the data from
> the healthy replica (data16) to the newly added DataNodes data2 and data20:
> {code:java}
> data2 0
> data16 976cd849
> data20 976cd849 {code}
> However, the checksum on DataNode 2 did not update automatically. I had to
> run the reconcile command multiple times before it eventually reflected the
> correct checksum (976cd849), which is not the expected behavior
> {code:java}
> data2 bc9276dc ← Incorrect
> data8 976cd849
> data15 976cd849 {code}
> Here, the DataNode 2 checksum is being updated incorrectly. dn-container.log
> {code:java}
> grep 10136 /var/log/hadoop-ozone/dn-container.log
