Hi All, I have got excellent results of dm-ioband, that controls the disk I/O bandwidth even when it accepts delayed write requests. In this time, I ran some benchmarks with a high-end storage. The reason was to avoid a performance bottleneck due to mechanical factors such as seek time. You can see the details of the benchmarks at: http://people.valinux.co.jp/~ryov/dm-ioband/hps/ Thanks, Ryo

Hi everyone, This is a new release of dm-ioband and bio-cgroup. With this release, the overhead of bio-cgroup is significantly reduced and the accuracy of block I/O tracking is much improved. These patches are for 2.6.28-rc2-mm1. Enjoy it! dm-ioband ========= Dm-ioband is an I/O bandwidth controller implemented as a device-mapper driver, which gives specified bandwidth to each job running on

Hi all, This is a good news for LVM users, especially for RHEL and CentOS users. You can control I/O bandwidth of your disks easily without hassle, because I've made RPM binary packages of dm-ioband and dm-ioband-config available at http://people.valinux.co.jp/~ryov/dm-ioband/binary.html The RPM binary packages are for Red Hat Enterprise Linux 5.x and CentOS 5.x. They were tested on CentOS

Hi Alasdair and all, This is the dm-ioband version 1.8.0 release. Dm-ioband is an I/O bandwidth controller implemented as a device-mapper driver, which gives specified bandwidth to each job running on the same physical device. This release is a minor bug fix and confirmed running on the latest stable kernel 2.6.27.1. - Can be applied to the kernel 2.6.27.1 and 2.6.27-rc5-mm1. - Changes from

Hello all, I've implemented a block device which throttles block I/O bandwidth, which I called dm-ioband, and been trying to throttle I/O bandwidth on KVM environment. But unfortunately it doesn't work well, the number of issued I/Os is not according to the bandwidth setting. On the other hand, I got the good result when accessing directly to the local disk on the local machine. I'm
