Created attachment 343592 [details] strace output Description of problem: It seems that blkiomon gets into problems when consuming data from blktrace on ia64 machine. Version-Release number of selected component (if applicable): RHEL5.4-Server-20090512.nightly blktrace-1.0.0-5.el5 kernel-2.6.18-141.el5 How reproducible: always Steps to Reproduce: # mount -t debugfs debugfs /sys/kernel/debug/ # blktrace -w 60 -d /dev/cciss/c0d0 | blkiomon -I 10 -h - blkiomon: endianess problem # strace -o output.txt blktrace -w 60 -d /dev/cciss/c0d0 | blkiomon -I 10 -h - blkiomon: endianess problem # time blktrace -w 60 -d /dev/cciss/c0d0 | blkiomon -I 10 -h - blkiomon: endianess problem real 1m0.164s user 0m0.003s sys 0m0.915s # umount /sys/kernel/debug/ Actual results: Expected results:
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
