reducing RF wen using token allocation algorithm

Hi,

I've set up cluster with:

3.11.2

30 nodes

RF=3,single dc, NetworkStrategy


Now i'm going to reduce rf to 2, but i've setup cluster with vnode=16 and allocation algorithm(allocate_tokens_for_keyspace) for the main keyspace (which i'm reducing its RF), so is the procedure still be 1. alter keyspace... and 2. run nodetool cleanup on all nodes?

Your approach is correct although I'd make sure that your repairs are
current and successful before running cleanups. FWIW it doesn't really have
anything to do with the token allocation algorithm. Cheers!
