First backup failed immediately. We are noticing two more things. First, the failed mount of today fails more often than other mounts. It is not the mount of the OS, but a second added disk (mounted in /dev/sdb1). I have attached the output for /etc/mtab and /etc/fstab of the specific machine that failed. Maybe it helps.
Secondly, backups always switch to read-only at almost the same time: near the end of the backup. I cannot say exactly when, but our backups usually take 4 hours. And failures are always (approx) within the last half hour. ** Attachment added: "mtab and fstab" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1470250/+attachment/4567116/+files/mount -- 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
