Could you manually try setting the scheduler? E.g. cat /sys/block/vda/queue/scheduler echo noop > /sys/block/vda/queue/scheduler cat /sys/block/vda/queue/scheduler Does that work? Or could you try the same from Ruby IRB? irb File.read("/sys/block/vda/queue/scheduler") File.write("/sys/block/vda/queue/scheduler", "noop") File.read("/sys/block/vda/queue/scheduler") -- You are receiving this mail because: You are on the CC list for the bug.
