a1dd8c87 failed after 70(!) hours (VSS backups started to fail after 17 hours or so, but the file system was remounted read-only after 70 hours total)
Another observation, something which h I also noticed in previous "bad" runs: Also almost instantly after starting backups, there were I/O errors on "/dev/sda sector 0" logged, with no obvious/immediate consequential failures, but the first I/O error on a non-zero sector caused a fs remount. Those errors were not in the good runs (or at least they weren't logged :P ) started run on d215f91-reverted -- 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
