believe. 2.4 is supported by DRBD still<SPAN class=009340214-22052005>,

It might be worth a try on the newer systems. THere are a lot of things
that need to be just right when you install DRBD. For one, you want to use
the same compiler version for it that you used on your kernel. If that has
changed or been upgraded since you built the computer, and you haven't compiled
a new kernel with it, this could explain stuff. Also, you must have the
exact same version of source as your running kernel. One thing to try to
be sure all things are equal, is to simply recompile your kernel with the source
that you now have, get it running, then delete and re-create the source
directory, and compile DRBD against it. Let us know how it
goes!</FONT></SPAN></DIV>

Again, I am not saying this is the BEST way to do it, because I am no uber
genious DRBD expert, but it is what worked for me. Once you get that
going with no error, do a "cat /proc/drbd" to confirm that it looks good,
then do a "drbdadm down all" and try to start it up from your init
script. You will also want to create a directory somewhere, and then
set up mount and umount statement in your init
script.</FONT></SPAN></DIV></BLOCKQUOTE>
