Hi,

We did this but with just two differences it wasn't 3.9 and and always a 3
.X version and we didn't keep the same ip.

We removed the dead node nodetool removenode

Installed Cassandra and configured it to as a new node (we have a playbook
for this) with the same conf that all the others.

Run a repair on each node

Run a cleanup on each node


I found this procedure if you wanna keep the same ip but I never tried it.

Regards,
Marco
