Hello. Does the somebody create scheduler for raid1 to add ability to
read data from all devices, for example i need to read from all
devices when have sequential read.
I found patches in 2012 from Robert Collins, Load balancing
reads on dmraid1 (and 01) arrays
why it not merged , does dm devel devs have plans to round-robin raid1
reading operations ?
iirc the patches showed no measurable performance gain.
Are we talking here about rather deprecated old dm mirror usage,
or a new raid1 (mdraid) ?
I assume new dm-raid target is using everthing what md raid provides.
