Hi, I have some problem here. Currently i have setup cluster on SAN. But when i attach uisng DRBD it’s said need to format. Or i need to unmount before adding disk in DRBD? I not familiar with SLES 11. I familiar with Red Hat only. Does any document refer to SP1? Please assist me. Thanks. ---

What shared storage are you using and how is it configured? [color=blue] > when i attach uisng DRBD it’s said need to format.
