Hi Magnus, Thanks, this is great news! I was worried that clearing a planned node removal would stop the node from which I was issuing the clear command, which would be bad. Sounds like I have nothing to worry about in that case.
On running cluster plan multiple times to generate a new plan: this is a little surprising since I think I’ve done that before but I haven’t observed it generating a new plan. I’ll try it again. Thanks for very quick response.
