i'm rebuilding my box with 2 drives, a 74gb raptor & a 200gb maxtor
want to use the small drive as system drive & the big one only for /home.

my scheme looks like this:
Code:

/dev/sda1 -- /boot      primary

/dev/sda2 -- (swap)     primary

/dev/sda3 -- /          primary

/dev/sda4 --            extended

/dev/sda5 -- /usr       logical

/dev/sda6 -- /opt       logical

/dev/sda7 -- /var       logical

/dev/sda8 -- /tmp       logical

/dev/sdb1 -- /home      primary?


i understand partitioning with fdisk so far, but my questions are:

how ( on which mount point ) do i have to mount /dev/sdb1?

and how would the corresponding line in /etc/fstab look like?

thanks again!

I fail to see why someone unsure about how to write an fstab for two drives feels the need to have a seperate /usr, /opt, /var, and /tmp. Do yourself a favor and lump most of those under /, with *possibly* a seperate /usr or /tmp depending on your needs. In particular, a seperate /opt will be useless in the vast majority of cases.... unless you need to keep your / partition ultra-small for some strange reason.

Anway, /dev/sdb1 should of course be primary and the line for /home will look something like this:
Code:
/dev/sdb1      /home           reiserfs    defaults,noatime        0       2

...... I'm still scratching my head over why someone who feels the need to subdivide / into a gazillion pieces can't figure out something so simple (relatively speaking). Is the handbook really that misleading nowdays?

BTW, 'fdisk' proper is sort of a relic. Try cfdisk...

ok, am ignorant as i'm, i figured out the mounting part ( not in the handbook btw ) would look like this:

Code:
# mount /dev/sda3 /mnt/gentoo
# mkdir /mnt/gentoo/boot
# mount /dev/sda1 /mnt/gentoo/boot
# mkdir /mnt/gentoo/usr
# mount /dev/sda5 /mnt/gentoo/usr
# mkdir /mnt/gentoo/opt
# mount /dev/sda6 /mnt/gentoo/opt
# mkdir /mnt/gentoo/var
# mount /dev/sda7 /mnt/gentoo/var
# mkdir /mnt/gentoo/tmp
# mount /dev/sda8 /mnt/gentoo/tmp
# mkdir /mnt/gentoo/home
# mount /dev/sdb1 /mnt/gentoo/home


is that right?

thanks again!

that should be right
I would recomend putting some of the partitions on the secound hard drive since you have plenty of space. Reason being there is a performance boost if /var, /home, and the swap are on a second drive in different partions. This way binaries are read off of one disk, and data is writen on the secound drive, in /home or /var. I would definitly put /var on your second hard drive as that will speed up portage noticably. Having some stuff in different partitions is good because it reduces fragmentation, and thus read times are improved. There are security advantages too because some partions can only be written to by the root user. Something else to keep in mind is data on the outer edge of a disk reads faster than the inner edge, I think.
These are my mount points
    /dev/hda1 /boot
    /dev/hda2 /tmp
    /dev/hda3 /
    /dev/hdb1 swap space
    /dev/hdb2 /var
    /dev/hdb5 /home
    /dev/hdb6 /home/[my home]/music
    /dev/hdb4 /mnt/ntfs

I read this when I was trying to figure this stuff out http://www.gentoo.org/doc/en/articles/partition-planning-tips.xml

You can't mount the extended partition.
