HI

I am new to DRBD and I meet problems when I issue "drbdadm create-md all" on
the drbd node.

Basic info is

    meta-disk /dev/sda5[0];
  }

ERROR MESSAGE is

[root at drbd01 ~]# drbdadm create-md all
v08 Magic number not found
md_offset 0
al_offset 4096

Found ext3 filesystem 
This would corrupt existing data.
If you want me to do this, you need to zero out the first part
of the device (destroy the content).
You should be very sure that you mean it.
Operation refused.
 
Command 'drbdmeta /dev/drbd0 v08 /dev/sda5 0 create-md' terminated with exit

Though I googled on the Internet, nothing useful turned up.

Any suggestions will be welcomed.

Thank You in Advance.
