Sorry to ask such a question but all my previous installs have been with a server with one hard drive. This one has two. I want to make full use of the space. I heard that raid 0 might be the answer but I also head it is very likely to break down. How else might I setup the OS or raid to use both hard drives or do I have to reconfigure Openvz?

Thanks for any help you can give

LVM is my favorite:

   Device Boot      Start         End      Blocks   Id  System
/dev/hda1   *           1          19      152586   83  Linux
/dev/hda2              20          25       48195   83  Linux
/dev/hda3              26          31       48195   83  Linux
/dev/hda4              32       19457   156039345   8e  Linux LVM

   Device Boot      Start         End      Blocks   Id  System
/dev/hdb1               1       19457       [all]   8e  Linux LVM

The first three partitions are for /boot:
3) temporary install boot
2) rescue boot
1) sys boot

The fourth partition of the first disk, and all partitions of other disks, are used for LVM. It's great for dynamically adding and dropping logical volumes.

  LV        VG   Attr   LSize   Origin Snap%  Move Log Copy%
  rescue    v0   -wi-a-   1.00G
  swap      v0   -wi-ao 512.00M
  sys       v0   -wi-ao   8.00G

It takes some effort to get comfortable with LVM, but the results are worthwhile. I resisted learning it at first, but now that I know how to, I always do.

Cool
