Has anyone experience of working with local disks or volumes with physical/logical block sizes of 4K rather than 512?
There seems to be KVM support for this (http://fibrevillage.com/sysadmin/216-how-to-make-qemu-kvm-accept-4k-sector-sized-disks) but I could not see how to get the appropriate flavors/volumes in an OpenStack environment? Is there any performance improvement from moving to 4K rather than 512 byte sectors? Tim
