Thanks for taking a look. One of the things that is painful about debugging this issue is how long it takes to manifest. It would probably require several weeks of testing a particular kernel version without seeing the issue before we could be reasonably sure that the problem is fixed. Also, testing in parallel can be quite resource intensive since we need 10-15 machines to drive the workload for a single machine under test.
Given this, I think we will spend a couple more days trying to come up with a better reproducer, one that can produce the issue in less time, or at least without requiring our application (and therefore our ZFS bits). If we can do that, we should be in a better position to test with other kernels. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1832384 Title: Unable to unmount apparently unused filesystem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1832384/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
