<DIV><FONT face="Courier New" size=2>Hi,</FONT></DIV>
<DIV><FONT face="Courier New" size=2></FONT> </DIV>
<DIV><FONT face="Courier New" size=2>I'm having trouble getting DRBD to run on
top of a software raid 0 or jbod device. Actually the problem is that DRBD can't
seem to get the exact size of the partition.</FONT></DIV>

<DIV><FONT face="Courier New" size=2>And because of this I kept getting
"access beyond the end of device" error. Should I manual set the disk size for
drbd for raid 0 and jbod? How do I do that?</FONT></DIV>
<DIV><FONT face="Courier New" size=2>But if I used raid 1, everything seems
ok.</FONT></DIV>
