2009-09-11Bug fix: handles disk device used multiple timesAlan D. Brunelle
There were issues in having the same underlying device being referenced multiple times (via different paths) when reporting storage I/O statistics. As an example: having two (or more) LVM2/DM volumes crafted out of the same MD array. This patch simply skips over any devices previously seen. Signed-off-by: Alan D.

2009-05-27Increase accuracy of disk utility percentageJens Axboe
If a job file contains more than one job that works on separate disks, then the job that finishes first will get more idle time accounted to it. Fix this by only doing disk util stats when we have files open on that device. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2008-09-30Aggregate slave device stats into the stats for master.Shehjar Tikoo
But do so by adding new fields in the stats line. We dont want the existing output format to get clobbered. The new fields in master device line which contain aggregated stats start with "aggr".

2008-09-30Add support to display slave device stats for software RAIDs.Shehjar Tikoo
When running tests on a device created using mdadm, the relevant disk statistics must also come from the individual disks that constitute the RAID, because the software RAID device is just a virtual device. This patch goes through the 'slaves' directory in the software RAID device's directory in /sys/block, gets a list of all the slave devices and creates a master-slave relationship between the virtual device and the actual disks. The individual slave disks' stats are displayed along with the master's disk stats at the end of the test.

2008-06-06Linux sysfs change broke fio disk lookupJens Axboe
/sys/block/<dev> is now a sym link to the real path, which broke our disk lookup. Fix it. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2008-05-30Seperate status timer setup from disk util timerJens Axboe
It's still the same timer and shared, but move it out of diskutil so we get proper status reporting on non-Linux. We also need to rearm the signal handlers on each signal. Move this to sigaction() next. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2008-03-07Fix bad sscan() -> scanf() conversionJens Axboe
Caused fio to stall waiting for disk updates. Also add --debug=diskutil debug option, to trace what diskutil is doing. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

Add an option to disable the disk stats. And only dump the disk stat header, if we actually have stats to show. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
