lvm2. The underlying device is an LVM partition. I added drbd to the
lvm2 filter. Would this be a good assumption?</FONT></SPAN></DIV>

<DIV></DIV>
<DIV><FONT face=Arial size=2><SPAN class=251192520-25082005>I began the
installation of a new pair of servers today so I downloaded drbd 0.7.12
for them. These servers were fully functional under drbd 0.6.x last
week, I just wiped them and installed RHEL 4 AS. Everything was ok for
the first hour or so, but now I'm getting this error from the kernel.
Ideas?</SPAN></FONT></DIV>
