Mathieu, As noted in LP:1538775, version 0.4.9-3ubuntu7.8 still isn't resolving the issue for me, as while my system does start (im not dropping to a rescue shell), the multipath daemon seems to be executed prior to the disks being discovered/udev starting and so it boots using sda for root instead of mpath. Running 'multipath -v5' post-boot shows that it wants to reconfigure pathing but cannot as the disks are in-use (understandably).
I've attached the dmesg log which shows when multipathd starts, the disks are detected, then udev starts. ** Attachment added: "dmesg" https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/1526984/+attachment/4564421/+files/dmesg -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to multipath-tools in Ubuntu. https://bugs.launchpad.net/bugs/1526984 Title: ISST-LTE: root mpath device unavailable after installation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/1526984/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
