5 the extra thoughts are that the better way of doing this would be to
6 create up
7 RAID1 physicaldisks1+2
8 RAID6 physicaldisks3,4,5,6
9
10 then put lvm on there as vg01 with two PVs, one on the raid1 virtualdisk
11 and one on the raid6 virtualdisk
12 you can then create new LVs and choose to put them on fast or slow
13 (raid1 or raid6)
14 you can then have system and archive data on raid6 and VM's on fast.
15 of course you could always have all 6 disks setup for raid0+1 and then
16 it woudl all be very fast
17
18 the general gist of what i'm trying to say is have the hardware raid
19 card do the hardware raid across the disks as required, then have LVM do
20 the partitioning of the storage. at the moment you have the hardware
21 raid doing the partitioning.
22
23 also i'd always recommend you have _inside the case_ a hotspare
24 configured to be global spare
