proxmox only uses disk1 to proccess vms
hello;
i created 34 vm useing a template i created first, i selected disk2 for half of them,
when i power on all of vms, server with 48GB ram mostly hangs and io over 80,
now server has cool down and you can see only only disk #1 is read/write , but i want like vmware each vm proccess from their own disks,
vms has been set writeback ! and ext4 mounted with nobarrier. (<i know risk but i have to)
i want qemu uses half disk1 and disk2 same time to reduce io usage
