I would suggest the following: Install lvm from http://www.sistina.com/lvm/ and install it following the INSTALL file. Eventually add reiserfs-patches to your kernel before rebulding it. Add the new drive, and create 10 partitions, type 8e, each 1G. # pvcreate /dev/hdb[1-9] /dev/hdb10 Then look how much space you need for /usr, /var, /tmp and create a volume group for them: If you need btween 3 and 4G, then do # vgcreate root_vg /dev/hdb[1-4] # lvcreate -n usr_lv -L <size_of_usr> root_vg # lvcreate ... (...means do this also for var_lv and tmp_lv) # mkreiserfs /dev/root_vg/usr_lv ... # mkdir /usr_new # mount -t reiserfs /dev/root_vg/usr_lv /usr_new ... # cd /usr # find . -print | cpio -dmp ../usr_new # ... Act like this with home_vg, local_vg or whatelse you need. Then change vou /etc/fstab to the new devices and reboot. Leave the root-partition and eventually /boot where it is. If everything is ok, mount says tha /usr is on /dev/root_vg/usr_lv ..., then you can pvcreate the old partitions and vgextend your volume groups. I left / (200G) non-lvm and ext2, so I can boot from a normal debian - CD, but there are also ways for putting root under lvm-control and reiserfs. If you need further assistance then send me a mail. Greetings, Christoph
