Hi
not that I tested this patch or the patch that followed (adding
blkiotune command) ... but the way I understand, the cgroup blkio
controller does only work for sync'd IO/queues.
quote blkio-controller.txt from 2.6.37:
Currently only sync IO queues are support. All the buffered writes are
still system wide and not per group.
When I last tested this (using manual cgroups commands), this seemed true.
So may I ask how you use this and how this helps in which setup?
Regards
Dominik
