[Solved] Suggestion for Partition/Mount Layout over Multiple Drives

I hope this is the correct place for this, if not I apologize.

I am looking for a suggested partition layout spanned over multiple drives. My drives are as followed:

1 - 120G SSD - Probably /boot?
2 - 3Tb Hard Drive
3 - 2TB Hard Drive
4 - 1Tb Hard Drive

I have no large data requirement for user directories as it will only be myself using it. As for large storage requirements, I have a 6Tb set aside for mass storage for /srv

Any suggestions would be greatly appreciated.

Re: [Solved] Suggestion for Partition/Mount Layout over Multiple Drives

I'd use LVM to manage the physical volumes (PVs) as a single volume group (VG) for managability (eg. resizing), RAID and SSD cache.

Example,

# where /dev/sda is the SSD and the others are 1TB partitions
vgcreate vg /dev/sda2 /dev/sdb1 /dev/sdb2 /dev/sdb3 /dev/sdc1 /dev/sdc2 /dev/sdd1
# 1TB non-redundant; 1TB RAID1; 2TB RAID5;
lvcreate -n throwaway vg /dev/sdb3
lvcreate -n better --type raid1 vg /dev/sdb2 /dev/sdc2
lvcreate -n best --type raid5 vg /dev/sdb1 /dev/sdc1 /dev/sdd1
# Cache RAID arrays evenly
lvcreate --cache --size 50% vg/better /dev/sda2
lvcreate --cache --size 50% vg/best /dev/sda2
