If once dm-ioband is integrated into the LVM tools and bandwidth can be assigned per device by lvcreate, the use of dm-tools is no longer required for users.
A lot of large data center users have a SAN, with volume management handled SAN-side and dedicated LUNs for different applications or groups of applications. Because of alignment issues, they typically use filesystems directly on top of the LUNs, without partitions or LVM layers. We cannot rely on LVM for these systems, because people prefer not to use that. Besides ... isn't the goal of the cgroups io bandwidth controller to control the IO used by PROCESSES? If we want to control processes, why would we want the configuration to be applied to any other kind of object in the system? -- All rights reversed. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
