Hi, All I've just notice one thing, when I am experiencing some errors in Kafka servers, I reboot the dev servers (not a good way), after reboot, I get into zkCli, I can see all the topics still exist. But when I get into kafka log directory, I found all data gone, see
root@DO-mq-dev:/tmp/kafka-logs-1/ui_test_topic_4-0# ll total 8 drwxr-xr-x 2 root root 4096 Jan 2 09:39 ./ drwxr-xr-x 46 root root 4096 Jan 2 10:46 ../ -rw-r--r-- 1 root root 10485760 Jan 2 09:39 00000000000000000000.index -rw-r--r-- 1 root root 0 Jan 2 09:39 00000000000000000000.log I wonder, if for some reasons, the server down, and restart it, all the data in hard drive will be gone? thanks -- Alec Li
