TrueNAS over iSCSI: Issue migrating VMs

[Lorne Guse]

I managed to answer my own question. I implemented the shared option and explicitly set it to 1. I found it in the documentation but got confused when it indicated that all network types are automatically marked shared in the background.

Migration now works as expected.

Subject: TrueNAS over iSCSI: Issue migrating VMs

I'm experiencing an issue migrating VMs.

I've been bouncing back and forth between the patch plugin and native plugin. I thought I had tested migrations with the new plugin in earlier versions.

Does my storage have to be explicitly marked as shared?
