Hello, I hope this is the write mailing list. I was debugging a container problem after upgrading kubernetes nodes on my cloud provider, and turns out it's an overlay fs related issue and has nothing to do with the container technology. I made a repro script and it consistently reproduce the issue. Thing breaks in the newer kernel version (5.10.134-13.1.al8.x86_64), and works in the older version (5.10.84-10.2.al8.x86_64). Test cases and the situation is explained in the script. --- #### Synopsis ## Things work as expected in 5.10.84-10.2.al8.x86_64 ## Things break as expected in 5.10.134-13.1.al8.x86_64
It seems those are our maintained kernels. -fsdevel is not the place to report downstream kernel (Alibaba Cloud Linux) bugs, could you help file the bug to: https://bugzilla.openanolis.cn/ (or I could help you file a bug there if needed). and we could discuss the root cause of this there and find a solution to resolve your current issue.

I have not yet bisect or upgraded to the latest kernel version, that's something I might be doing next, but since I am on Alicloud, upgrading the kernel is not the easiest thing I could do. I did some searches here and there for similar problems but to no avail. I am also> reaching out to Alicloud support. I hope if this is a known problem
Very sorry to hear that. Thanks, Gao Xiang
