Re: Correct repair job


Hi,
Yes, it needs to run on every node. This may help - https://www.datastax.com/dev/blog/repair-in-cassandra 
Consider using '-full' to avoid incremental repair whatsoever. 
Check the -dc, -dcpar and -local options for controlling its behaviour across DCs please - https://docs.datastax.com/en/cassandra/3.0/cassandra/tools/toolsRepair.html

Pranab

Hello,

I am looking to run 'nodetool repair -pr' for my 30 node Cassandra cluster.
My question is, do I need to run that command on every one of the 30 nodes?

How about if I have multiple DC's, can a single repair job apply too all nodes/DC's?
