Understanding EC and replication factor

[Lucas12138]

Hi community,

We're using RS-6-3-1024k for our replication config.
Example log:

However, on recon, we saw for the open keys,
the replication factor is 6, replication type is 1048576 and type is fso.

How do we understand the meaning for the things above?
Our disk usage is very high. So, we wonder if we're leveraging the EC replication's benefits of storage saving

• The pipeline looks good.
• Can you please provide Ozone version and attach a screenshot of Recon? Sounds like a UI bug.
• EC RS-6-3-1024k saves space for files larger than 1.5MB.

sure, please see recon UI screenshots attached

[adoroszlai]

Can you please also share the version of Ozone you are using?

[Lucas12138]

We're using 1.4.1

Thanks. Filed HDDS-13835 for the Recon UI issue.

Marking @adoroszlai's reply as the answer since this is a bug. Will be taking a look at this, thanks @Lucas12138 for bringing this forward.
