Hi, what's your version of TiUP and `tiup dm`? also @lucklove PTAL
currently tiup-dm doesn’t support SSL. welcome to file a feature request in pingcap/tiup

I have used chaosmesh to try imitate a bad disk environment, but not effective to reveal bugs. We might try use failpoint with percent probability to inject into etcd API,...
(removed the BUG label because we need further investigating if it's has been fixed)
This problem is caused by dump unit always returns true in https://github.com/pingcap/dm/blob/50841fb066119153c3b33a92ff9e57959e6ff914/dumpling/dumpling.go#L197-L199 Maybe we should check dump files in local disk
