------------------------------------------

Hi [~sdeka]
{quote}Instead, the desired behaviour is to stop accepting new append requests on the group

For OM case, when any transaction is failed, we should fail and stop that OM. For OM case stopping ratis server might be the correct way to do.

> This is related to HDDS-1739 which detects and reports IO failures during applyTransaction.
> Currently, the StateMachineUpdater in response to a failed applyLog/applyTransaction operation triggers a shutdown of the Ratis server.
> Instead, the desired behaviour is to stop accepting new append requests on the group. For the case of Ozone, the state machine will initiate destruction/closing of the Ratis group - this is implemented as a part of HDDS-1739.
