Hi all, iobandctl has been updated to v0.0.3. This version of iobandctl enables you: To use the configuration files to configure I/O bandwidth control settings, To apply I/O bandwidth control to multiple disks which share the I/O bandwidth, To apply the new bandwidth control policy which has been implemented on dm-ioband v1.0.0. See http://people.valinux.co.jp/~kaizuka/dm-ioband/iobandctl/ for more details. 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/bwctl/ Changes from previous version: * Configuration file support o config subcommand is added. o It is possible to configure your I/O bandwidth control settings using your configuration file. * Multiple disks support o −−bind option is added on "create" subcommand. o It is possible to apply I/O bandwidth control to multiple disks which share the I/O bandwidth. o It's certain that two or more Logical Units contained in the same SCSI target device share the I/O bandwidth. You are able to distribute the bandwidth among the partitions involved in these Logical Units. * New bandwidth control policy support o policy subcommand is added. o The new policy "weight-iosize" do I/O bandwidth control based on the size of I/Os instead of the number of I/Os, which is the existing and default policy named "weight-iocount". * Particular devices name support such as certain raid devices o Support for logical drive names such as "/dev/cciss/c1d0" and raid device names such as "/dev/md0". o This simply means that iobandctl has come to treat such names properly now, though it couldn't do that in previous version. o It needs you to understand which device share the I/O bandwidth with which other device, and configure proper settings using --bind option.
