This appears to be reproducible again on 18.10, except at very early boot (premount):

Breaking at premount, to have multipath load before LVM gets to load the devices leads to a system that finishes booting but appears to be in read-only filesystem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1480399 Title: LVM over multipath setups fail to boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/1480399/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
