<HTML> <HEAD> <TITLE>Blacklist broken?</TITLE> </HEAD> <BODY> 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. device-mapper-1.02.63-3.fc15.x86_64 device-mapper-multipath-0.4.9-15.fc15.x86_64 device-mapper-libs-1.02.63-3.fc15.x86_64 2.6.38.8-35.fc15.x86_64 mpath0 (36001ec90ee4ee600105ac65e04e84e61) dm-0 DELL,PERC 6/i size=279G features='0' hwhandler='0' wp=rw `-+- policy='round-robin 0' prio=1 status=active `- 2:2:0:0 sda 8:0 active ready running [root@bonjovi ~]# blkid | grep boot /dev/sda1: LABEL="/boot" UUID="8ed92bb6-0ddb-4fbc-907d-fdf12e5550a3" TYPE="ext3" SEC_TYPE="ext2" /dev/mapper/mpath0p1: LABEL="/boot" UUID="8ed92bb6-0ddb-4fbc-907d-fdf12e5550a3" TYPE="ext3" >From multipath.conf: blacklist { wwid 36001ec90ee4ee600105ac65e04e84e61 devnode "/dev/sda" devnode "/dev/sda1" } 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? -brian </BODY> </HTML>
