Hello all, I'd like to try I/O shaping using ioband, but it doesn't seem to be working properly for some reason. I have one disc partition used as LVM PV, VG on top of it. I created two 1GB LVs for tests: iob1, iob2 Then I setup ioband using following commands: echo 0 2097152 ioband /dev/mapper/vg-iob1 iob 0 0 none weight 0 :40 | dmsetup create ioband-iob1 echo 0 2097152 ioband /dev/mapper/vg-iob2 iob 0 0 none weight 0 :10 | dmsetup create ioband-iob2 When I measure throughput using hdparm --direct -t on one of the ioband devices, i get ~61MBps. If I measure it on both devices concurrently in loop, throughput settles on ~30MBps on every device, so it seems that it's divided equally. What am I doing wrong? thanks a lot in advance nik PS: I'm using 2.6.26-rc8+ioband-1.1.0 patch -- ------------------------------------- Nikola CIPRICH LinuxBox.cz, s.r.o. 28. rijna 168, 709 01 Ostrava tel.: +420 596 603 142 fax: +420 596 621 273 mobil: +420 777 093 799 www.linuxbox.cz mobil servis: +420 737 238 656 email servis: servis@xxxxxxxxxxx ------------------------------------- -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
