You got the point. I previously thought that testifies are on disk, but actually they are in tmpfs and consuming huge memory. That’s why OOM killer would kick in when writing large files in tests. > Good, so 2GB memory is not enough for zfs-linux (I assume you ran this test > with 2 cores like I did) Yes, I always use 2 cores. > > I agree we shouldn't spend too much time on squeezing it into the *current* > defaults.

If the tester itself does not occupy too much RAM, the real requirement for resources is now probably several gigabytes of disk space (currently it’s ~10GB). I will give more feedback once new results come out. Thanks, -- Shengqi Chen
