Uma Maheswara Rao G commented on HDDS-7177:
-------------------------------------------
Ok, I think this case may be when first stripe failed in some of block groups?
If this case is consistently reproduce able, then enable debug, so that we will
know there are stripe failures and rewritten to new nodes. In this case that
previously failed stripe blocks left out. Just wanted to make sure this is what
happening. If that is the case, it's not hard data itself, we need to figure
out a way to delete them.

> We found that even deleted all the EC keys in the cluster and flushed the
> transactionbuffer, there are still some blocks left. They are all of 1M size.
> The config is rs-10-4-1024k
> This could be replayed.
