Hi I've just been attempting to use DRBD with Xen on CentOS 5.6 and Ubuntu 8.04 LTS using the drbd:resourcename syntax for disks and I've run into some problems. First, if I try to use that syntax the pygrub complains about it as Redhat (I've been debugging this on the CentOS side) haven't backported the drbd: syntax changes to pygrub. I found a pair of patches to /usr/bin/pygrub and a blkif file on the xensource bugzilla entry http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1438 but it would appear to me that the patches are broken. They work and allow a guest using disk [ 'drbd:resourcename ...' ] to be used but starting the one VM puts *all* DRBD resources on that xen host into primary state. I've created a working version of the script but the original patch is so badly broken that I'm sure that anyone who tried to use it would have noticed so I can't believe that it's still broken 2 years after that bugzilla! Is anyone else using drbd: syntax for Xen VM's? Does /usr/bin/pygrub use 'drbdadm sh-resources ' + file around line 682? Or has it already been fixed in a different way? Thanks. Trevor Hemsley
