1st Night Backups Ran okay, with no strange SCSI errors. The following was logged into syslog:

The Linux SCSI layer does not automatically adjust these parameters. So we're still getting the messages about, hey, something changed on the Disk, but I can live with that for the price of a proper VSS snapshot. Again, this is with the 3.19 -39 kernel on 14.04.2 LTS. I'll keep an eye on it. I guess I'll wait for production changes, but it's so tempting :-) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1445195 Title: [Hyper-V] Kernel patches for storvsc Status in linux package in Ubuntu: Triaged Status in linux source package in Precise: Triaged Status in linux source package in Trusty: Triaged Status in linux source package in Utopic: Triaged Status in linux source package in Vivid: Triaged Status in linux source package in Wily: Triaged Bug description: Storage driver performance updates for vivid K.
