Milos, did you say this was NOTABUG due to missing "-o -" for blktrace? # blktrace -w 5 -d /dev/sda | blkiomon -I 10 -h - blkiomon: endianess problem # blktrace -w 5 -d /dev/sda -o - | blkiomon -I 10 -h - # if you agree let's close it :) Thanks, -Eric I agree. Could you close it please? need to pipe that output somewhere for blkiomon to get what it expects :) Thanks, -Eric |
