    Description

      Description of problem:

      While attempting to install 2430 SNOs from ACM via ZTP using the assisted-installer, 188 (and possibly more clusters) failed to complete install because etcd operator is not available due to leader election lock. There are an additional 6 other clusters with this failure but also have an machine-config operator degraded failure was well.

      Version-Release number of selected component (if applicable):

      Hub OCP - 4.12.10
SNO OCP - 4.13.0-rc.5
ACM - 2.8.0-DOWNSTREAM-2023-04-17-13-54-41

      How reproducible:

      ~8% of the installs seem to have failed because of this reason
