Description

This is happening because anaconda doesn't create /etc/multipath.conf by default, and without it, the multipath modules isn't installed. You can create a multipath.conf file by running # mpathconf --enable Unfortunately, multipath doesn't tell you that there is no config file if the kernel module isn't loaded. Also, mpathconf --enable doesn't load the module (or chkconfig multipathd on and start the daemon). All these things need to happen. Then you will get a helpful error message telling you to run mpathconf, and when you do, multipath will be working correctly. This should be fixed in anaconda-13.21.40-1 , which is in snap 5. Please test and verify. I just installed nfs --server=storage.bos.redhat.com --dir=/vol/engineering/devarchive/redhat/rel-eng/RHEL6.0-Snapshot-5/6.0/Server/x86_64/os I still get the same error. # multipath -ll May 25 15:03:00 | DM multipath kernel driver not loaded device-mapper-multipath-0.4.9-21.el6 changed the code around so that it will instruct you to run mpathconf. Running # mpathconf --enable will give you a default configuration file, if you don't have any, and it will load the module, and chkconfig multipathd on. If you do # mpathconf --enable --with_multipathd It will also start multipathd immediately. If you don't need to modify the default configuration file, this is the way to go. Otherwise, after running mpathconf, you should edit the file to your liking, and then run # service multipathd start Barry, can you attach your ks.cfg ? Created attachment 417225 [details]
This is the kickstart file for the install.
Since this bug was opened against device-mapper-multipath, and the change for that has been committed, I've cloned a bug to be used for the anaconda fixes. The new bugzilla is #596804 Red Hat Enterprise Linux Beta 2 is now available and should resolve the problem described in this bug report. This report is therefore being closed with a resolution of CURRENTRELEASE. You may reopen this bug report if the solution does not work for you. |
