Re: [gentoo-user] About ready to move /usr, /var and /home to LVM.

[Matthew Marlowe]

fyi, as someone who has played around quite a bit with most of the
ways to configure a home workstation, I find the best config currently
is:

Dedicated Fast Enterprise 2TB drive -> /, swap,  and /boot (ext4)
Six 2TB Reliable SATA Drives in RAID10 -> /home (ext4 with appropriate
chunksize/etc)
Two 2TB Reliable SATA Drives in LVM VG -> /archive, other lvm volumes
I can afford to lose and may need to change sizes for.

No worrying about any bootup complications/initrd or seperate /usr or
/var on workstation, all the important personal data is on reliable
storage, lots of free space for big projects. Backups are on separate
disks from data.
Ext4 over RAID seem happier without lvm. Maybe a few years down the
road btrfs will be complete, I'll be able to switch to that.

Only complications of above is a) careful monitoring of boot disk, b)
with so many drives, chassis needs good air flow/power, and c) unless
/tmp or /var put on lvm, all gentoo compiles are limited by i/o of
boot disk (this isn't a problem for me now, but perhaps when I upgrade
to faster cpus with more cores..).
