Hello,
Why do I get the following warnings (?) on a new 3-node CrateDB cluster? I’m just getting started and the data disks are almost empty, I didn’t create any tables yet.
I also set gateway.expected_nodes and gateway.recover_after_nodes to 3 as recommended.
loadgenerator001@eris:~$ source /home/loadgenerator001/venv/cratedb/bin/activate
(cratedb) loadgenerator001@eris:~$ crash --verbose --hosts 192.168.239.30 --username energytix
