I just upgrade an FC13 system to FC15, and now multipath is grabbing the system drive before the normal fsck can run, which is causing the machine to not boot. I get the message: "Filesystem mounted or opened exclusively by another program? " Now, I can simply control-d to continue, but why is multipath grabbing the drive? I've blacklisted it every way I can, using devnode, using wwid, it simply ignores it and continues to create a path map for /dev/sda.

>From multipath.conf:

}
devnode_blacklist {
wwid 36001ec90ee4ee600105ac65e04e84e61
devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"
devnode "^hd[a-z]"
devnode "^cciss!c[0-9]d[0-9]*"
devnode "sda"
devnode "/dev/sda"
}
I've even tried blacklisting by /disk/by/uuid. What does it take to get multipath to quit grabbing this disk?
