Description Chris Lober 2008-06-04 16:05:25 EDT
Description of problem:

The devnode_blacklist {} keyword has been depricated in the /etc/multipath.conf


2006-03-13 multipath-tools-0.4.7 shortlog :
    * add per-device product-string blacklist
    * add a device blacklist
    * add a wwid blacklist
    * deprecate the "devnode_blacklist" keyword ub favor of "blacklist"

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Enable the device_blacklist {} keyword in /etc/multipath.conf
2. Install device-mapper-multipath-0.4.7-17.el5
3. service multipathd start   dies after running and multipath commands fail
Actual results:
[root@ncldl38072 ~]# grep devnode_blacklist /etc/multipath.conf
devnode_blacklist {
[root@ncldl38072 ~]# rpm -q device-mapper-multipath
[root@ncldl38072 ~]# service multipathd start
Starting multipathd daemon:                                [  OK  ]
[root@ncldl38072 ~]# ps -ef|grep multipath
root     19067 18803  0 16:02 pts/1    00:00:00 grep multipath
[root@ncldl38072 ~]# multipath -ll
error parsing config file
[root@ncldl38072 ~]# 

Expected results:
[root@ncldl38072 ~]# multipath -ll
mpath0 (3600601608c751a005804047e1687dc11) dm-11 DGC,RAID 5

Additional info:

Changing devnode_blacklist{} to blacklist {} in /etc/multipath.conf resolves the
issue but I think it would be better to support both keywords during the RHEL5
Comment 1 Chris Lober 2008-06-04 16:11:58 EDT
I did more research and this is not a bug.

It was an error in my install process.

I attempted to close this as NOTABUG but it would not let me.
