> The ChunkInfo command displays an EC Data Block which is invalid.
> !Screenshot 2024-11-14 at 6.05.22 PM.png!
> Block-ID 113750153638531250 should be available only on 1 DataNode as the
> other 2 are EMPTY Data Blocks and the size of the block is less than the
> stripe size i.e. 1MB.
> But in the chunkinfo console output, we can find that it shows 2 Data Blocks
> with their File locations.
