[K12OSN] Server Partitioning

[Petre Scheie]

Since you have six disks, you could arrange them in three, RAID 1 (mirroring) pairs, 
which would give you full redundancy.  With that in mind, I'd devote one pair to the OS 
and swap: Set the swap to 3GB to match the available RAM (the rule of thumb used to be 
swap should be double the RAM, but since performance in LTSP suffers so much when you 
push into swap, you REALLY don't want to actually make much use of swap); and use the 
rest of that disk pair for the root (/) partition.  Put /home on another pair of disks. 
  And as for the third pair...I don't know, keep around for emergencies.  I think 8GB 
for /home ought last quite a while in a school context.
