[DRBD-user] DRBD setup problem

[Darlan Segalin]

Hi, to solve this problem, go to the steps

    * you created your filesystem before you created your DRBD resource, or
    * you created your filesystem on your backing device, rather than your
DRBD, 


dd if=/dev/zero bs=1M count=1 of=/dev/sdXYZ; sync 
drbdadm create-md $r
drbdadm -- -o primary $r
mkfs /dev/drbdY
