Hi, I am trying to use blktrace (mentioned in the documentation for CONFIG_BLK_DEV_IO_TRACE) to collect some disk I/O statistics. It works at first, but every time I kill it with Ctrl-C and then try to restart it, the program aborts with the message
BLKTRACESETUP: No such file or directory Failed to start trace on /dev/hda my exact sequence of commands is this $ sudo blktrace -d /dev/hda -o - | blkparse -i - | tee trace-log (some output...) (Ctrl-C) $ sudo blktrace -d /dev/hda -o - | blkparse -i - | tee trace-log2 (abort...) I 'git clone' the blktrace source code from git://git.kernel.dk/blktrace.git and compiled it on my machine, the last 'git log' item is like this commit 2885ecaa19a04ab9980896d1a849cdae9238b7d1 Author: Vincent Legoll <[EMAIL PROTECTED]> Date: Mon Jul 30 15:23:43 2007 +0200 ... output from 'blktrace --version' blktrace version 0.99.2 I think this will be enough for you to identify my blktrace version. any idea about this problem?
