In context with this earlier post I had https://www.mail-archive.com/user@cassandra.apache.org/msg56122.html We run repair on each node in the cluster with the -pr option on every table within each keyspace individually. Repairs are run sequentially on each node Repairs fail for all nodes for all tables with -pr option But if we run the repair with DC option (-dc localdatacenter) for local datacenters on all nodes for all tables, then all repairs are successfully. Is this indication that the repairs are good? can we proceed with with adding new nodes and decomissioning nodes even when individual repairs fail but the DC repairs work Is there anything else other than scrub that can be performed to fix the repair issues? Thanks Leena
