[Bug 927540] Re: multipath ignores blacklist in multipath.conf

[Lukasz Szulik]

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
