| iostat is only list the disk performance, not the partitions. So, if you 'ls -l /dev/sd*', you can find that like follow: btw-rw---- 1 root disk 11, 0 Jan 30 2003 /dev/scd0 So, this device should be dev11 in iostat output. |

| I have five disks sda sdb sdc sdd sde but iostat show dev8-0 dev8-1 dev8-2 dev8-3 dev8-4 那我怎麼知道dev8-0是對應到哪一個device |

| btw-rw---- 1 root disk 11, 0 Jan 30 2003 /dev/scd0 这个就是 dev11-0了， 我想你那个会有不同的吧。 |
