If you have some random IO workload, it's very possible that btrfs bookend extents are causing the problem.

Is there a way to check the booked extents of a certain file? I have a bunch of VM images that could be the issue, but I'd like to check this hypothesis. -- You are receiving this mail because: You are on the CC list for the bug.
