You should re-install the O/S. You can re-use the existing volumes, but you should have the installer remake (as in mkfs.ext2/3) the root (/), /var, and /usr file systems. You can keep /home, etc. as is (assuming it is a separate file systems. If you have enough space available in your volumn group, you can create a new root file system for the 64-bit system and use that. You can re-use the /boot file system if you plan on making things 'dual boot'. You can do this (except create new logical volumns, unless you are using the GUI installer)) from the 'custom layout' screen in the installer. > > Thanks, > > Kai > > > _______________________________________________ > CentOS mailing list > CentOS@centos.org > http://lists.centos.org/mailman/listinfo/centos > > > -- Robert Heller -- 978-544-6933 / hel...@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@centos.org http://lists.centos.org/mailman/listinfo/centos
