It gets complicated when you have RF > 1, because a subrange can involve
multiple nodes, and a node can't run multiple repairs concurrently for
the same table. Multiple DCs also complicates things, as the
describering command doesn't separate the token ranges by DC. In my
opinion, it's best to
If you can pick ranges on your own correctly, then you can do that way. In
my opinion a ready made tested solution is available, I think it should be
used.

Does describering not give the correct sub ranges for each node ?

Also try to use Cassandra reaper (as Kane also mentioned) for subrange
repair. Doing subrange repair yourself may lead to a lot of trouble as
calculating correct subranges is not an easy task.

-pr on all nodes takes much longer as you'll do at least triple the amount
of merkle calculations I believe (with RF 3) and tends to be quite
problematic.
Subrange is the way to go, which is what cassandra-reaper will do for you
if you have it set up.

Hi,
We are on open source 3.11.5 .
We need to repair a production cluster .
We are using num_token as 256 .
What will be a better option to run repair ?
1. nodetool -pr (Primary range repair on all nodes, one node at a time)
OR
2. nodetool -st -et (Subrange repair , taking the ranges for each nod
