Comment #12 worked for me! Thanks Chris.mn. However, I believe the more canonical way of omitting the PIDs to kill would be to use the /run/sendsigs.omit.d directory. Interestingly, /etc/init.d/mdadm already adds mdmon to this, just only on stop, not start. I don't understand why and this may be a mistake.
In any case, I have attached a patch to /etc/init.d/mdadm that adds the mdmon PID to the sendsigsomit.d directory on start. The check_raid in umountroot is also needed for me and I have included that in the patch ** Patch added: "mdadm.patch" https://bugs.launchpad.net/ubuntu/+source/mdadm/+bug/1320402/+attachment/4270840/+files/mdadm.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1320402 Title: mdadm resyncs imsm raid in "Normal" state To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mdadm/+bug/1320402/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
