New kernel 2.2.18 and a cook list
Hi all,

I write this email, asking Marcello if he could make a resume of all
the patches for a stable drdb implementation on a 2.2.18 kernel... I think that
with th new kernel there are some patches no more needed, and in many person
there are a lot of confusion.

Thanks Marcello!!!

Oh, I forgot about that bug, sorry.

David, if you have time could you please setup a kernel with the NMI
oopser (from http://people.redhat.com/mingo/nmi-patches/) on a SMP box and
see if it gives us oops when the secondary node crashes?

Also is good to remember that drbd resync is not safe with journalling
filesystems.

Really? Why do we think this? Has it been tested with an SMP secondary
and protocol C?

The node does not crash, it simply hangs. Sysreq works sort of and seems
to show scheduling back and forth between a pair of drbd threads, so I
assume it is some sort of deadlock or starvation issue, but haven't looked
further. I mean to, but other things keep getting in the way...
