| |
Hi all,
These are new releases of dm-ioband and blkio-cgroup. The major changes of these releases are: - dm-ioband can be configured through the cgroup interface. The bandwidth can be assigned on a per cgroup per block device basis. - The event tracing is supported that helps in debugging and monitoring dm-ioband. - A document for blkio-cgroup is available at Documentation/cgroup/blkio.txt.
This series of patches consists of two parts: dm-ioband v1.12.1 dm-ioband is an I/O bandwidth controller implemented as a device-mapper driver and can control bandwidth on per partition, per user, per process, per virtual machine (such as KVM or Xen) basis.
blkio-cgruop v9 blkio-cgroup is a block I/O tracking mechanism implemented on the cgroup memory subsystem. Using this feature the owners of any type of I/O can be determined. This allows dm-ioband to control block I/O bandwidth even when it is accepting delayed write requests. dm-ioband can find the cgroup of each request. It is also for possible that others working on I/O bandwidth throttling to use this functionality to control asynchronous I/O with a little enhancement.
The patches can be applied to both the current device-mapper development tree and 2.6.31-rc3.
The list of the patches: [PATCH 1/9] I/O bandwidth controller and BIO tracking [PATCH 2/9] dm-ioband-1.12.1: All-in-one patch [PATCH 3/9] blkio-cgroup-v9: The new page_cgroup framework [PATCH 4/9] blkio-cgroup-v9: Refactoring io-context initialization [PATCH 5/9] blkio-cgroup-v9: The body of blkio-cgroup [PATCH 6/9] blkio-cgroup-v9: The document of blkio-cgroup [PATCH 7/9] blkio-cgroup-v9: Page tracking hooks [PATCH 8/9] blkio-cgroup-v9: Fast page tracking [PATCH 9/9] blkio-cgroup-v9: Add a cgroup support to dm-ioband
Please visit our website, the patches and more information are available. Linux Block I/O Bandwidth Control Project http://sourceforge.net/apps/trac/ioband/
I'd like to get some feedbacks from the list. Any comments are appreciated.
Thanks, Ryo Tsuruta
