nodetool repair -pr

[Igor Zubchenok <ig...@zubchenok.com>]

Hi!

I want to repair all nodes in all datacenters.
Should I run *nodetool repair -pr* at all nodes of a SINGLE datacenter or
at all nodes of ALL datacenters?

It depends on your data model. -pr only repair primary range. So if there
is a keyspace with replication 'DC2:3', and you run repair -pr only on all
nodes of DC1, it is not going to repair token ranges corsponding to DC2. So
you will have to run on each node.

According docs at
http://cassandra.apache.org/doc/latest/operating/repair.html?highlight=single


*The -pr flag will only repair the “primary” ranges on a node, so you can
repair your entire cluster by running nodetool repair -pr on each node in
a single datacenter.*
But I saw many places, where it is noted that I should run it at ALL data
centers.

Looking for a qualified answer.

I want to repair all nodes at all data centers.

Example:
DC1
 nodeA
 nodeB
 nodeC
DC2
 node D
 node E
 node F

If I run `nodetool repair -pr` at nodeA nodeB and nodeC, will all ranges be
repaired?
