/cc can you PTAL? It seems related to new test in
flaking regularly -
actually, I'm not sure this is a test-only race... it looks like self mutates , and that is called in a goroutine in parallel with other methods that access rootDirectory: I suspect this has always been a race, and the unit test is exercising / catching it more
moving the filepath.Clean to init time: and changing the check in setupDataDirs to be a validation rather than a mutation: might resolve the immediate race
/assign
is open to fixing it. The data race we find here should be fixed. However, is another one that we need to fix. I add a new commit to fix that as well.
did you see that race as well or did you just see the issue opened? that was in a code path that should be feature gated so I wouldn't have expected it to trigger in the kubemark unit tests
I may mixed problems together. Yes. will not trigger in the kubemark unit tests. Using stressing, I find the data race cannot fix the problem completely. Then I saw and cherry-picked the fix to my PR. But the hollowNode test still flakes and I looked into it and find it is the volumeManager problem. is just another potential data race in .

the rootDirectory and volumeManagerSyncTime race fixes are easy to reason about and fix code that looks like it could really race in currently enabled-by-default code looks like a real race in disabled-by-default code. I'll defer to kubelet folks and whether to mix that fix into
I think I should drop that fix. This will make things more clear.
