Hi All, Debian Lenny, Xen 3.2.1 I''ve setup DRBD resources from a domU I had, and it has synced up correctly. If I shut the machine down on node1, I can successfully start it on node2 and all is well. However if I live migrate the domain, it successfully transfers the domain across and is running on the other node, but will stay in the suspended "migrating-domain" on the first node. The log seems to be paused at the following: [2010-06-03 11:06:53 3289] DEBUG (DevController:151) Waiting for devices vtpm. I don''t use vtpm, it''s not enabled in my config, is it normal to show when migrating if not in use? If I destroy the domain that is suspended it drops of the xm list and is still happily running on the node it was live migrated to. Has anyone seen this before and got around it in some way?

Yea I''ve got that as follows;
net {
allow-two-primaries;
after-sb-0pri discard-zero-changes;
after-sb-1pri discard-secondary;
}
It all migrates correctly, it just won''t destroy the original host
correctly!

It''s worth noting that if I do a normal migrate it works correctly.

You could try the alternative DRBD transfer scripts here: http://www.antibozo.net/xen/qemu-dm.drbd I had a similar issues and they fixed it. They work for HVM too. PVM have issues when more than one hard disk is specified in the config file.

Robert is right, if I drop the swap disk out of the config the live migration works correctly (only 1 disk). In terms of using this replacement disk, has anyone done this on Debian lenny? I can''t seem to locate pygrub. Just incase... Has anyone else got PVM''s using DRBD with more than 1 disk live migrating on Debian Lenny?

You didn''t mention how you use the disk. In my experience it''s easier to simply use phy:/dev/drbd/by-res/ symlinks (which is available since drbd 8.3, I think) compared to using drbd:/ (which I never got to work) or phy:/dev/drbd* (which is not informative).

While this has the POSSIBILITY of introduing corruption (due to simultaneus write to both nodes), it''s no more dangerous than mapping an external SCSI LUN to two hosts. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

What DOESN''T work for me is live migrate under heartbeat control. Using the Xen OCF resource with a basic configuration, all works fine: crm_resource --migrate takes down the resource on one node, brings it up on the specified node; taking down a node yields an automatic startup on the failover node. On the other hand, setting allow_migrate to true (allowing for live migrate), results in failures whenever crm_resource --migrate is invoked. Never did track this down (since my primary use is failover, I don''t really care about live migration). Miles -- In theory, there is no difference between theory and practice.
