I got some time and did a rebuild of dmraid in Xenial, which completed. So I am not really understanding why running dmraid in 16.04 does claim to find nothing while it does succeed in 14.04. I am attaching the two debs here just in case an actual rebuild produces something different than before.
The dmraid command seems to have verbose and debug options. Maybe those help. Or you could check /var/log/syslog to see whether running dmraid produces some error messages... ** Attachment added: "dmraid_1.0.0.rc16-4.2ubuntu3_amd64.deb" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1611277/+attachment/4718231/+files/dmraid_1.0.0.rc16-4.2ubuntu3_amd64.deb -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1611277 Title: Kernel Shipped With Ubuntu 16.04.1 Cannot Recognize fakeRaid To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1611277/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
