Hello all,
I ran blktrace for 14 devices using the command below and there were
80 files generated for each device and 1120 files in total.
blktrace -d /dev/sda /dev/sdb /dev/sdl /dev/sdm /dev/sdn /dev/sdo
/dev/sdq /dev/sdp /dev/sds /dev/sdr /dev/sdt /dev/sdw /dev/sdv
/dev/sdu -w 900 -a write -a read -b 8192
I tried running a blkparse on the blktrace binary files as shown below
and I get bad trace magic 7746165 for pretty much all of the files
and no parsing happens.
blkparse -i ./*.blktrace.0 -d ./bp.bin -o bp.txt -w 0:900
Why just the .0 trace file? Not sure where the magic error is coming
from, but that part is definitely a bit odd. If you run:
blkparse -i sda -d ./bp.bin -o bp.txt -w 0:900
does it still fail?
