Bernd,

 =09The ENBD project requires a kernel patch for 2.6 support and I=20
would like to remain with the vendor supplied (and "blessed" kernel) for=20
support reasons.

 =09Since I cannot provide feedback on the latest version of the=20
kernel and I don't want to have an "unblessed" kernel, I've opened a=20
ticket with RedHat attached to my support contract for this problem.  I=20
mainly posted my question here to see if this was a known issue with 2.6=20
in general or NBD-specific.

 =09I had not heard of "DRBD" before now, but it looks interesting.  I=20
am looking into it further.

Thanks,
 =09Roy Keene
