Re: [Xen-users] xm migrate headache



This could be really, really bad.  I'm actually surprised you haven't experienced any issues with the filesystem already.  In a active/active (primary/primary) DRBD setup, my understanding is that you need to treat this exactly the same as if you had a SAN volume you were presenting to more than one host, which means a cluster-aware filesystem.  I don't know that this is what's causing your (live) migration issues, but it probably won't be long before you start seeing some filesystem corruption on your DRBD volume.

See the following page:
