Lokesh Jain commented on HDDS-1868:
-----------------------------------
[~swagle] Thanks for working on this! I think we should include pipeline
reports from followers as well. Otherwise there can be cases where followers
have not yet registered or can not communicate to SCM but the pipeline is still
active in SCM. In RATIS-678 if we include leader information in the api we can
use it to update leader information in SCM as well.
> Ozone pipelines should be marked as ready only after the leader election is
> complete

> Ozone pipeline on restart start in allocated state, they are moved into open
> state after all the pipeline have reported to it. However this potentially
> can lead into an issue where the pipeline is still not ready to accept any
> incoming IO operations.
> The pipelines should be marked as ready only after the leader election is
> complete and leader is ready to accept incoming IO.
