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



Hi All,

I am trying to mirror RAID 5 ( /dev/md0) to RAID 5 ( /dev/md1) using device mapper. But i don't know
the syntax of mirror to put in device mapper table. i tried various combinations to solve it but of no help.
I got following error


  *****************************************
  device-mapper ioctl cmd 9 failed: invalid argument
  command failed

*******
so can anybody help me by sending example of mirror option for device mapper table.


  regards,
  - Kiran
