Jane Deng created CASSANDRA-15719:
-------------------------------------
Summary: The primary range repair should be run on every datacenter
Key: CASSANDRA-15719
URL: https://issues.apache.org/jira/browse/CASSANDRA-15719
Project: Cassandra
Issue Type: Bug
Components: Documentation/Blog
Reporter: Jane Deng
In the Cassandra document page:
[http://cassandra.apache.org/doc/latest/operating/repair.html], there is an
explanation which makes confusion on users' side:
{quote}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.
{quote}
This made confusion that "running nodetool repair -pr on each node in a single
DC" was sufficient to do a full repair on a multi-DC cluster.
The correct way to use the primary range repair should be
{quote}if you are using “nodetool repair -pr” you must run it on *EVERY* node
in *EVERY* data center, no skipping allowed.
{quote}
Please make a doc fix. Thanks.
