Upgrading from 3.7 to 3.11.1 will not involving any major changes. It can be achieved without any downtime and it should not impact on Cassandra clients. You can test the upgrade on a test cluster to be sure if you are considering to upgrade prod.

I don't have a JIRA reference handy but there are quite some issues in this version. Considering your scenario, it is highly recommended that you should upgrade to 3.11.1. Although, you have mentioned that upgrading is not an option, I would like to tell you that On 19 April 2018 at 23:19, Leena Ghatpande <lghatpa...@hotmail.com<mailto:lghatpa...@hotmail.com>> wrote: we have 8 node prod cluster running on cassandra 3.7. Our 2 largest tables have around 100M and 30M rows respectively while all others are relatively smaller. we have been running repairs on alternate days on 2 of our keyspaces. We run repair on each node in the cluster with the -pr option on every table within each keyspace individually. Repairs are run sequentially on each node These were working fine, but with no change on the systems, they have started failing since last month. The repairs have started failing for each table on every node with no specific error. I have tried running scrub on every table and then running repair , but still the repair fails for all tables. Our smallest table with only 100 rows also fails on repair. But if I run the repair with DC option (-dc localdatacenter) for local datacenters, then the repairs are successfully. Is this indication that the repairs are good? we would still want the repairs to work on individually tables as expected. Need help trying to get the repairs to work properly as we have a big migration planned for june . Upgrading cassandra is not an option right now.
