Re:[dm-devel] help : device-mapper ioctl cmd 9 failed: Invalid argument




Hi All,


Thanks for immediate attention on my mail.

  The fdisk output (partition table)for my machine is as follows:
*****************************************


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 fd Linux raid autodetect /dev/hda10 476 522 377496 83 Linux

*********************************

I want to create volume using partions /dev/hda7 and /dev/hda8

  Now i changed my dmsetup (table file ) file which is as follows
******************************:

  0       409600  linear  /dev/hda7       0
  0       409600  linear  /dev/hda8       0

*******************************
  [Since two disk of same size]

But when I execute the command

# dmsetup create dmsetup dmsetup

It gives the following error message

  device-mapper ioctl cmd 9 failed: Invalid argument
  Command failed

I am not able to understand , whats going wrong in this ...

Please guide me to solve this problem ...

  Thanks and Regards
       -  Kiran.
