Hello,
I'm rebuilding my home server ( mainboard GA-M85M-US2H, athlon x2 245) based on ubuntu server.
I can assign 5 drives to the server:
2x 1To
1x 1.5 To
1x2To
1x 500Go
I'm trying to find the best layout based on mdadm raid: ( Please no LVM at this time)
Basically
- Raid 5
- minimal wasted space,
- minimal number of mountpoints
My current plan is
1 To |________|
1 To |________|
1.5 To |________|____|
2To |________|____|____|
0.5To |____|
-> md0 : Raid5 4x 1To-> 3To net
-> md1 : Raid5 3x 0.5 -> 1To net
-> 500gb without redundancy
I was wondering: Would it be possible to build a Raid 5 on top of a JBOD ? to get this layout
|________|________| 2 x 1to
|____________|____| 1.5 + 0.5
|_________________| 2 tO
-> I'd have 6to brut-> 4To in raid5 with one joker ( 1 drive can fail without loosing data)
Thanks for reading and commenting ...
