I have a big cluster around 20 node, and data very big
I see doc say best do repair regularly and sequentially
current I execute nodetool repair -pr
need 1 day per node
and I thank my cluster have data issue… there are many write fail
I hope can do repair as soon as possible
so I want to ask
can I exec repair in multiple node same time ?
It would be better if you used ScyllaDB Manager for the job as it knows to handle repair parallelism and intensity with ease, but I see you have a 20-node cluster.
That said, you can repair multiple nodes at the same time. You could also simply run nodetool repair
once and let it eventually complete. However, you’ve already said you currently are having write failures, so ideally you’d rather check on these before adding more background work to your running cluster.
