We have drbd8 running - if we delete multipaths access to storage (ie. simulate a failure) drbd goes diskless - we use this status to trigger a live migrate of all domU to the other host.
So in theory we could have up to 20 domUs migrating at once. In practice we have done 8 crm_resouce -M at once on the command line. The first one triggers a migrate_to/migrate_from - all other do migrate_from/start? All the cli-prefer constaints are created OK. The cluster is running in asymmetric mode so everything is controlled via fail counts. -----Original Message----- From: [email protected] [mailto:[email protected]]on Behalf Of Andrew Beekhof Sent: Monday, 9 March 2009 7:03 PM To: General Linux-HA mailing list Subject: Re: [Linux-HA] live migrate On Thu, Mar 5, 2009 at 21:09, David Pinkerton H <[email protected]> wrote: > CIB as follows Looks sane enough. There's no colocation or ordering rules that would prevent a migration from occurring... Did any resource actions fail? (Look for ERROR: in the logs). Actually, re-reading the original email, what do you mean by "If I execute several migrates at once"? Running subsequent crm_resource -M commands before the resource has finished migrating? I can imagine that wouldn't work. _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems This email and any attachments may contain privileged and confidential information and are intended for the named addressee only.
