i ended up with the following solution: as i have the only one array and it is not used for system boot, i've added AUTO -all to the /etc/mdadm/mdadm.conf
and created the file /etc/init/mounted-root.conf mgr@nas:~$ cat /etc/init/mounted-root.conf description "assemble MD with external bitmap" start on mounted MOUNTPOINT=/ env MOUNTPOINT=/ task script mdadm --stop /dev/md0 mdadm --assemble --scan end script after that array assembles correctly with external bitmap on boot. i'm not sure about the correctness of the solution, so, please comment! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/803737 Title: mdadm doesn't start array with external bitmap To manage notifications about this bug go to: https://bugs.launchpad.net/mdadm/+bug/803737/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
