This is not a bug of multipathd. I gues that you are using DELL MD3xxx multipath installer. This install script provide new initrd that have one significant change - add multipath.conf (the same as they add in standard /etc) in initrd environment.
So - at the initrd stage when lvm starts (with default lvm.conf @initrd) they links local filesystem lvm to multipath device. When chroot phase is in time your config defined in root /etc/multipath.conf can't remove PERC multipath dev because they are already in use by root fs. Solution - please swap initramfs (@ /boot/..) to the original (it's now rename) and at the initrd stage no multipath devices of PERC will be created. You multipath.conf in rootfs /etc/multipath.conf are OK). regards LS -- 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/927540 Title: multipath ignores blacklist in multipath.conf To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/927540/+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
