My grub.conf is pointing to sdb1 for /. I've corrected to use /dev/vg0/lv1. But after rebooting, I am getting the same error. I guess I need to rebuild initrd.img file. How do I rebuild that file?

You need to rebuild the initrd and make sure the grub.conf file is up-to-date (has the right thing for the root parameter). > > > > Thanks, > > > > - xinhuan > > MIME-Version: 1.0 > > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos > > -- Robert Heller -- 978-544-6933 / heller at deepsoft.com Deepwoods Software -- http://www.deepsoft.com/ () ascii ribbon campaign -- against html e-mail /\ www.asciiribbon.org -- against proprietary attachments _______________________________________________ CentOS mailing list CentOS at centos.org http://lists.centos.org/mailman/listinfo/centos
