Sorry for the long delay in posting results but I did want to share what we've learned. 1) The failures happen during the VSS Snapshot/checkpoint creation process. You can reproduce the errors by doing manual VSS snapshots. 2) The heavier the VM load, especially I/O, the more likely the error will occur. 3) Every kernel posted (including the Willy) share the same problem - differences were not significant between them. 4) During snapshot creation, even RHEL hits a bump. There's a small delay in response times but nothing that causes errors. Installing LIS 4.0 doesn't make a difference.
Unfortunately, I can't follow-up with further testing. After figuring this out we cancelled the migration to Hyper-V and invested further in our VMware infrastructure. :( Thanks! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1470250 Title: [Hyper-V] Ubuntu 14.04.2 LTS Generation 2 SCSI Errors on VSS Based Backups To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1470250/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
