I ran iozone on two groups with 500 and 1000 as weights on the same parition and set fairness to 1 in sysfs for the partition. I used a record size of 4 (default) and tried to run it on a file size of 1G. BTW, I don't see anything about weights being multiple of an expected figure documented anywhere. I tried weights of 1024 (similar to the scheduler and got shouted back at :) ). Does the documentation patch specify the expected range for weights? -- Balbir -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
