Comment 2 Evgeny Slutsky 2022-06-07 08:04:05 UTC 
yes, it's for the default existing machine set, 
did you try to scale down to 0 workers? what happens if you scale down from 3 to 2 workers?
Comment 3 michal 2022-06-07 08:21:54 UTC 
if I scale from 3 to 2 workers it's working fine
Comment 4 michal 2022-06-07 09:55:59 UTC 
after verifying with Evgeny this is the correct behavior.
when scale down the default machineset to 0, the last worker can't delete it because there is no other machineset to move all running pods.
