Hello List,
I need a configuration with 2 Server and live migration.
* so I need drbd ?!
I have changed the xml file to:
<disk type=''block'' device=''disk''>
<driver name=''drbd''/>
<source dev=''test''/>
<target dev=''xvda'' bus=''xen''/>
</disk>
But now I can''t boot anymore.
<bootloader>/usr/bin/pygrub</bootloader>
<bootloader_args>-q</bootloader_args>
Who can help?
Mike

... I just read this: disk = [ ''drbd:*resource*,xvda,w'' ] - pygrub from Xen 3.3 forward, and the domUloader.py version that ships with SLES 11 *do* support this syntax. Under these circumstances, you must use the traditional phy: device syntax and the DRBD device name that is associated with your resource, not the resource name. That, however, requires that you manage DRBD state transitions outside Xen, which is a less flexible approach than that provided by the drbd resource type. :-( any other ideas how to handle this? 2010/11/1 Mike Sievers <saturngeist@googlemail.com>> Hello List, > > I need a configuration with 2 Server and live migration. > * so I need drbd ?! > > I have changed the xml file to: > <disk type=''block'' device=''disk''> > <driver name=''drbd''/> > <source dev=''test''/> > <target dev=''xvda'' bus=''xen''/> > </disk> > > But now I can''t boot anymore. > <bootloader>/usr/bin/pygrub</bootloader> > <bootloader_args>-q</bootloader_args> > > Who can help? > > Mike >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Anyway, Pacemaker or Heartbeat can take care of this. If you create a resource for DRBD and then one for Xen and the collocate and order them, the DRBD resource is activated on the resource you want the Xen guest to start on or migrate to.

In order to get it work correctly you must use the kernel & ramdisk directive in the domU config like this name = "atmail" memory = "1024" vcpus=1 cpus = ["2-3"] # VCPU0 runs on CPU2, VCPU1 runs on CPU3 -------------------------------------------------------Start Here --------------------------------------------------------------------- kernel = ''/boot/test/vmlinuz-2.6.18-194.8.1.el5xen'' ramdisk = ''/boot/test/initrd-2.6.18-194.8.1.el5xen.img'' root = ''/dev/VolGroup00/LogVol02'' disk = [ ''drbd:atmail,xvda,w'' ] -------------------------------------------------------End Here --------------------------------------------------------------------- vif = [ ''mac=00:16:3E:29:13:AE,bridge=xenbr0'' ] vfb = [ ''type=vnc,vnclisten=0.0.0.0,vncdisplay=1'' ] on_reboot = ''restart'' on_crash = ''restart'' -- View this message in context: http://xen.1045712.n5.nabble.com/can-t-boot-xen-vm-with-drbd-tp3244849p3245436.html Sent from the Xen - User mailing list archive at Nabble.com. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
