Hi, I am able to run that tests: I am running RHEL ppc64le, latest k8s with go1.8, probably something specific to do with SLES?
I still get the error on SLES, updated the code to latest and using go1.8, maybe it is SLES (or my machine?) specific talks about /tmp space, not sure if its related..
Hi , Some investigation into this i found that the issue is due to the hardcoding on line 32 in (similar from comments here: ) I changed it to remove the hardcoding (patch attached) and the test case passes on SLES as well, i am not sure if the patch is appropriate so requesting you to review it as appropriate
Hi Vaibhav, Have you raised any PR on it? If raised, reviewing would be easier. There is one thing I noticed: In the above code, you are comparing actual used value with total of empty directory usage and expected block size. When you create a new file like "f1 created here with only "Hello World", it consumes 4K in Ubuntu/RHEL. This size is same as for an empty directory. What is this size in SLES? So, either you hardcode this value(conditional for SLES) or call getExpectedBlockSize() on f1 file path instead of tmpDir.
Hi I have created the PR for the patch as suggested.. I have also changed the original patch slightly to use getExpectedBlockSize() on f1 file path instead of tmpDir as you suggested as that I think would be the right way to do it.. Thanks! Vaibhav
