Fedora Core 4 uses LVM; you can find out information about this at: http://sources.redhat.com/lvm2/ Most of the information in the LVM HOWTO is still relevant, but see also the manpages for the commands, which will be more up to date. For RAID, FC4 uses mdadm for everything. See the manpage. This program does not need a configuration file, but if you want your mirrored RAID partitions monitored, you'll need one. If you don't have one, you can create one using: # mdadm --detail --scan > /etc/mdadm.conf You should then add a line: MAILADDR you@xxxxxxxxxxx and run: # chkconfig mdmonitor on This will enable monitoring of your RAID partitions and will send you an email if anything happens to it, e.g. one of the drives fails. > 2. What are the GUI and non-GUI commands? GUIs: system-config-lvm for LVM. None for RAID yet. Non-GUIs: see answer to first question. > 3.
