Well, the issue filed here, is autocreated mdadm.conf prevents autodetection of cold- and hotplugging.
I found out not only the ARRAY lines, but also the homehost prevents autotection of arrays. The homehost feature may have been good to prevent systems with global "mdadm --assemble --scan" booting from unsyncing partly pluged in arrays and device name switchtichg in the old days. With UUID checking in mdadm, udev and dynamic device names working, we need a way to unset the homehost, to set it to "any" or some other way so "mdadm --incremental /dev/%k" will really setup all completed arrays that are attatched when it is called from udev rules. Something like: HOMEHOST "" in mdadm.conf or --homehost=any on the comandline. -- mdadm.conf is crated with explicit ARRAY statements prevents hotplug autodetection https://bugs.launchpad.net/bugs/252345 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
