DRBD 9.0.x doesn't support dual-primary mode. This is basic functionality necessary for live migrations using Xen. Not having this makes Leap 42.3 useless for Xen servers.
Recommend making the latest 8.4.x packages available until 9.0.x supports live migration.

"With current DRBD-9.0 version running in Dual-Primary mode is not recommended... In DRBD-9.1 it will be possible to have more than two primaries at the same time."
I did have some conversation regarding deliver both drbd8.4 and drbd9, but we decide to include drbd9 only to avoid the possible confusing. I did try dual-primary in some early version of drbd9, the basic functionality looks fine. I suggest you try the dual-primary on drbd9 for live migrations in test environment first and report any issue you meet. And please not to use more than two nodes in dual-primary, i think this scenario is not ready yet. -- You are receiving this mail because: You are on the CC list for the bug.
