Whilst the symptoms are clearly demonstrated, the root cause has not been trianged.
This may still be a regression in the kernel & userspace stacks, or not. It is not clear, how this can be bisected. All Ubuntu releases have been so far affected and internally we do not have access to this many devices - neither on z, or other architectures accessible by a single system. It would be useful to request IBM QA to rerun this particular testcase on 18.04 LTS to check if things are still just as broken, or have become better or worse. This will at least gives us the trend line for this stress test. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1571707 Title: The created partitions can be seen in the system only partly when partitioning 256 FCP devices with multipathing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1571707/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
