-----------------------------------------
Thank You [~shashikant] for providing an initial patch. I am working on
rebasing the patch, and also working on patch limitation of considering
checksumBlock size equal to chunk size.

>
> This Jira is to add CRC for chunks data.
> Right now, in chunkInfo, data is just byte array. We want to change this as
> below:
> _message Data {_
> _required string magic =”Tullys00” = 1;_
> _required CRCTYPE crcType =_ _2__;_
> _optional String LegacyMetadata = 3; // Fields to support inplace data
> migration_
> _optional String LegacyData = 4;_
> _optional ushort ChecksumblockSize = 5; // Size of the block used to compute
> the checksums_
> _repeated uint32 checksums = 6 ; // Set of Checksums_
> *_repeated byte data = 6;_* _// Actual Data stream_
>
> _}_
>
> _This will help in error detection for containers during container scanner._
