Hi, everyone, iobandctl has been updated. It came to be able to deal with LVM Volume Groups. iobandctl is an administration tool to realize disk I/O bandwidth control using dm-ioband, which is an I/O bandwidth controller implemented as a device-mapper driver. You can find dm-ioband at: http://people.valinux.co.jp/~ryov/dm-ioband Changes from previous version: * LVM support. o You can specify a Volume Group for the device name on "create" subcommand. Ioband devices are created per LV involved in the VG. o "create" subcommand has come not to try to create already existing ioband devices. This helps you to create an ioband device which will map on to newly added Logical Volume. o You can specify Logical Volumes for the device name on "weight" subcommand. o You can specify Volume Groups or Logical Volumes for the device name on "group", "showconfig", and "status" subcommand. o You can specify a Volume Group or a Logical Volume for the device name on "destroy" subcommand. Now, it is possible to delete each ioband device, not all ioband devices involved in the specified device. * Fixed a bug, when resetting ioband device statistics counter. Limitations: * iobandctl does not support the "weight-iosize" policy yet, which has been newly added to dm-ioband v1.0.0.
