Re : will Unsafeassaniate a dead node maintain the replication factor
hi;
would unsafeassasinating a dead node maintain the replication factor
like decommission process or removenode process?
thanks

If it is using vnodes then just run nodetool repair . It should fix the issue related to data if any.
And then run nodetool cleanup

Thanks Surabhi. Decommission nor removenode did not work. We did not
capture the tokens of the dead node. Any way we could make sure the
replication of 3 is maintained?

Re: Re : will Unsafeassaniate a dead node maintain the replication factor

You have to do few things before unsafe as sanitation . First run the nodetool decommission if the node is up and wait till streaming happens . You can check is the streaming is completed by nodetool netstats . If streaming is completed you can do unsafe assanitation .
To answer your question unsafe assanitation will not take care of replication factor .
It is like forcing a node out from the cluster .
Hope this helps.
