@f-bosch, @lauwersm, we appreciate your patience. We've looked into storvsc and vss and have been trying to reproduce the problem, and while we seem to have lowered the occurrence of the problem, have not eliminated it.
However, since the last storvsc update, we have fixed a number of issues in the 3.19 and 4.2 kernels. If not for a rushed CVE, those kernels would be GA at this point, but they are going into -proposed for release this weekend. Since you are on 14.04, I recommend testing on the lts-wily kernels, especially after the update goes out. # apt-get install --install-recommends linux-virtual-lts-wily linux- tools-virtual-lts-wily linux-cloud-tools-virtual-lts-wily (and reboot) This will move you to the 4.2 kernel, and after the latest update goes out, you will be running Hyper-V components from the 4.3 upstream kernel. On the next point release of 14.04, the plan is to switch the recommended kernel to lts-wily anyway, so you are just getting ahead of the rush a little. -- 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
