Running nodetool repair --partitioner-range simultaneously on all nodes in the 
cluster will indeed be a problem, and the symptoms will vary widely based on 
node state / write load / compaction load. This is one of the times when the 
right answer is "don't do that" until the project comes up with a way to 
prevent you from doing it in order to protect you from yourself.

Starting cassandra Service with Binary Disabled.

[Pranay akula]

Hi,

It is possible to disable binary in configuration when re-starting
cassandra service, instead of disabling it using nodetool once the node is
up.



Thanks
Pranay.

Re: nodetool repair failure

[kurt greaves]

You need check the node that failed validation to find the relevant error.
The IP should be in the logs of the node you started repair on.

You shouldn't run multiple repairs on the same table from multiple nodes
unless you really know what you're doing and not using vnodes. The failure
you are likely seeing is that multiple repairs are trying to occur on the
same SSTable, which will cause the repair to fail.
