Since RHEL 6.1 External Beta has begun, and this bug remains unresolved, it has been rejected as it is not proposed as exception or blocker. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux. Is this udev again? Does upstream code manage any better? Jon is the mirror code properly synchronizing with udev? Snapshots of mirrors (cluster or otherwise) is not fully supported. I will never be fully supported. Snapshots of mirrors will have to wait for the next mirror implementation (i.e. "raid1") to be complete. |
