Thanks ! dm-ioband isn't upstream. Best to ping original authors from valinux if you're still interested in it. If you have a need for bandwidth control Vivek Goyal has developed throttling support in the block layer. Vivek's work has been merged for upstream inclusion in Linux 2.6.37. See the following for documentation on throttling support: http://git.kernel.org/?p=linux/kernel/git/axboe/linux-2.6-block.git;a=commit;h=2786c4e5e54802c3 If you'd like to try it, it is available with the following: git clone git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux-2.6-block.git cd linux-2.6-block git checkout -b my_for-next origin/for-next Mike -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
