PVE Installation on Server with 4 disk

[olkern]

hello community,

I have an easy question (I hope so). I want to bild up a server with 4-core CPU and 4 HD SATA in the system. I can´t use the onboard controller for RAID. If I install the PVE on the system I only can see and use the first HD in the system. How can I add the other 3 disk to the system and use it for virtual mashines? What version of the PVE should I use 1.9 or 2.0?

If any question please call me


thx

Hi,
depends on you usage.
The best thing is to get an real hardware raid-controller and use the 4 disk in a safe raid-level (5 or 10 for speed).

To expand your disksspace you can:
a. simply extend your volume-group pve with the remaining disks and extend your data-lv (see also "man lvm").
b. define a new lvm-storage
c. if you have an second server, you can use DRBD (network raid-1) with some disks and provide so shared storage (for online-migration).

Perhaps you should use one disk for backup (but better on a different (safe) place).
