While we're not completely certain this is the smoking gun, I've observed that in the logs being posted here that there are no freeze/thaw operations taking place when the issue occurs. The commits that @jrp identified, fix messaging between the VSS utility driver and the host; and will hopefully ensure expected freeze/thawing of the filesystem during backup.
In our internal testing with the latest Linux-next kernel (which contains these commits) we were unable to hit this issue using scripts from @jsalisbury. We look forward to hearing back from the testing. -- 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
