[dm-devel] Re : help: device mapper table syntax for mirror option

[kiran dalvi]

Hi All,

  I am trying to mirror two hard disk partitions of 200MB each with 
following devicemapper table settings

  ***********
        0 819200  mirror core 1 1024 2 /dev/hda7 3363831808 /dev/hda8 
3573547008
  ***********
  and  i am getting the following error.

  device-mapper ioctl cmd 9 failed: No such device or address
  Command failed


  This is my partition table.


        Disk /dev/hda: 255 heads, 63 sectors, 1240 cylinders
        Units = cylinders of 16065 * 512 bytes

        Device Boot    Start       End    Blocks   Id  System

        /dev/hda1   *         1       261   2096451    6  FAT16
        /dev/hda2           262       522   2096482+   5  Extended
        /dev/hda3           523       535    104422+  83  Linux
        /dev/hda4           536      1240   5662912+  83  Linux
        /dev/hda5           262       390   1036161    1  FAT12
        /dev/hda6           391       400     80293+  83  Linux
        /dev/hda7           401       425    200781   8e  Linux LVM
        /dev/hda8           426       450    200781   8e  Linux LVM
        /dev/hda9           451       475    200781   8e  Linux LVM
        /dev/hda10          476       499    192748+  fd  Linux raid 
autodetect
        /dev/hda11          500       522    184716   fd  Linux raid 
autodetect

  Please suggest me what's going wrong with my mirror option argument or 
anything else to be included
  in table file.

  Thanks and kind regards,
           - Kiran
