Hello everyone,
We are running cassandra cluster inside containers over Kubernetes. We have
a requirement where we need to restore a fresh new cluster with existing
snapshot on weekly basis.
Currently, while doing it manually. i need to copy the snapshot folder
inside container and then run sstab
Hello Pradeep,
Actually the key here is to know if your cluster has the same token ranges
distribution. So it is not only the same size but also the same tokens
match node by node, from cluster source to cluster destination. In that
case, you can use nodetool refresh.So after copy all your sstable
Hello Jean,
I am running cassandra 3.11.1.
Since i dont have much cassandra operations experience yet, I have a
follow-up question - how can i ensure the same token ranges distribution ?
Do i need to set initial_token configuration for each cassandra node ?
Thank you for the quick response.
Hello,
Basically, every node has to have the same token range. So yes you have to
play with initial_token having the same numbers of tokens per node like the
cluster source. To save time and if you dont have any constraints about the
name of the cluster etc. you can just copy and paste the complet
Thank you very much Jean. Since i don't have any constraints, as you said,
i will try copying the complete keyspace system node by node first and will
do nodetool refresh and see if it works.

Make sure the new cluster has a different cluster name, and avoid copying
system.peers if you can avoid it. Doing so risks merging your new cluster and
old cluster if they’re able to reach each other.

Hello Jeff,
Thank you for the reply.
One doubt - If i copy the /var/lib/cassandra one to one from source cluster
to destination cluster nodes and change the cluster name in configuration
and delete system.peers table and restart each cassandra node, do you think
the cluster will come up properly.
