Hello everyone.
I was wondering if there is any way to mount lets say /hd1 to my VE along with more drives? I am very curious how to do this so i dont have to have huge partitions for my system when i can split them. I am running centos 5 32 bit but plan on going to 64bit and my ve is running a wonderful centos4.4

thanks everyone.

You should use LVM on the Hardware Node. This way you can add a physical drive to a logical volume easily, to increase capacity. And if you are running a server, I strongly recommend using a RAID1 array for redundancy. HDDs do fail.

yes of course... ill be running a raid 10 split into partitions. So use a LVM and how do i configure it on the VE?

i want to have like

Filesystem Size Used Avail Use% Mounted on
simfs 639G 470G 136G 78% /
simfs 700G 670G 30G 90% /hd2

on my HN of couse.. hell i wouldnt mind if it was /hd2 on the ve but on the actual server it was /home2/hd2

let me know.

Using LVM, you'd add the 2nd hard drive to the VG, and then increase the size of the LV, then increase the size of your / partition. However, I suggest the use of a separate partition for /vz. It may be delicate to increase the size of /.

If you just want to mount additional things inside of your VE, as long as they are already accessible from the hardware node, you can just use:
mount --bind {hn mountoint} /vz/root/{VEID}/desired/mount/point

You can do this within multiple VPSes too. --bind mounting works in non-OpenVZ enviroment too.

Please note that the /vz/root/{VEID} is empty when your VPS isn't running so you have to do your bind mount at some point after the VPS has started up and the /vz/root{VEID} area is alive.
