@f-bosch Hi Frederik, about the second issue you mentioned ("The more data getting on the disk, the higher the spikes are...requests that involve write operations tend to have these characteristics") in #54, it looks there is a storage I/O performance downgrade somehow.
Do you think if it's related to the backup issue? If not, do you think if we needs special I/O patters to trigger the perf downgrade? -- 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
