[Xen-users] drbd integration in Xen3.3(Ubuntu)
Hi, it seems that Xen3.3 in Ubuntu Hardy is missing integration with drbd: I get - Error: "Block device must have "phy", "file", or "tap" specified to type" when I try ''xm create test.cfg". VM ''test'' has in config file ''drbd'' resource as block device. disk = [''drbd:test-swap,xvda1,w'', ''drbd:test-disk,xvda2,w'' ] Does anybody have success with this type of configuration on Ubuntu Hardy?

Re: [Xen-users] drbd integration in Xen3.3(Ubuntu)
The problem is that xm doesn''t recognize ''drbd'' as blok device type; Since drbd-8.0.6 it is allowed to use drbd resource as VBD. Ubuntu Hardy''s drbd version is 8.0.11 In my configuration ''test-swap'', ''test-root'' are lvm partitions, defined with full path in drbd.conf as resources. Such configuration gives (according to drbd manual) nice feature - automatic change done by Xen between Primary/Secondary during migration.

Maybe the attached patch will work for you. This works for my paravirtualized domUs, but not fully virtualized domUs. #matt _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] drbd integration in Xen3.3(Ubuntu)
Just tried it, as well as tried to compile: python /usr/lib/python2.5/py compile.py *.py - still getting the same error. Some debugging shows that - when I run ''xm create test.cfg'' - fail comes from /usr/lib/python2.5/site-packages/xen/util/blkif.py xen-utils-3.3 xen-hypervisor-3.3 kernel 2.6.24-24-xen Longina On Thu, 27 Aug 2009, Matt wrote:> Longina Przybyszewska wrote: >> >> On Thu, 27 Aug 2009, Matt wrote: >> >>> Longina Przybyszewska wrote: >>>> Hi, >>>> it seems that Xen3.3 in Ubuntu Hardy is missing integration with drbd: >>>> >>>> I get - >>>> Error: "Block device must have "phy", "file", or "tap" specified to >>>> type" >>>> when I try ''xm create test.cfg". >>>> >>>> VM ''test'' has in config file ''drbd'' resource as block device. >>>> >>>> disk = [''drbd:test-swap,xvda1,w'', ''drbd:test-disk,xvda2,w'' ] >>>> >>>> Does anybody have success with this type of configuration on Ubuntu >>>> Hardy? >>> >>> I had the same problems with my block-iscsi script.

Re: [Xen-users] drbd integration in Xen3.3(Ubuntu)
Hi,
you have to add ''drbd'' in
/usr/lib64/python2.5/site-packages/xen/xend/server/blkif.py at line 59
..
else:
try:
(typ, params) = string.split(uname, '':'', 1)
if typ not in (''phy'',
''file'', ''drbd'', ''tap''):
raise VmError(
''Block device must have "phy",
"file", "drbd" or
"tap" ''
''specified to type'')
...
remove /usr/lib64/python2.5/site-packages/xen/xend/server/blkif.pyc und
restart xend or reboot.
