Hello, I'm fighting with weird issue. When I was tweaking IO scheduling and QoS with ionice I took notice that there is written "none" inside of all drbd's scheduler nodes in sysfs (/sys/block/dbrd*/queue/scheduler). It seem's like no io scheduler is available fot drbd devices at all. Could anybody explain me what does it mean, please? I think it's in conflict with chapter 13.3.3 of documentation which is about setting io scheduler for drbd resource to "deadline" to improve io performance. Btw writing 'cfq' or whatever to that file has no effect. Details here: http://pastebin.com/77FNEfxG Many thanks!
