To help see if this is an issue in the hv_storvsc driver; I took the storvsc driver code from 3.13.0-34.60 (presumably a good build) and applied it to the 4.2.0-27 kernel (presumably a bad build). Ran tiobench with backups and was able to repro after about 48 hours.
This implies that either: 1) The bad commit is not in the hv_storvsc driver. 2) 3.13.0-34 is not a good build as we previously thought. I'll wait to hear if other people can repro this issue on 3.13.0-34. The storvsc driver code I took for this snapshot => http://kernel.ubuntu.com/git/ubuntu/ubuntu- trusty.git/tree/drivers/scsi/storvsc_drv.c?id=3402ec8cbd984e8e2a1f99b51ec6a15a23328223 -- 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
