Installation Error

[BrusE]

Hi

When I try to install proxmox I got a this message

"unable to create volume group at /usr/bin/proxinstall line 501"

My machine:

AMD Opteron 2.0GHz
6 750GB RAID 5
8GB memmory

anyone?

Is there any additional info on the console (press CTRL-ALT-F2 to switch to the log console)

Thats OK so far, any other errors?

 

[BrusE]

Re-reading the partition table ...

If you created or changed a DOS partition, /dev/foo7, say, then use dd(1)
to zero the first 512 bytes: dd if=/dev/zero of=/dev/foo7 bs=512 count=1
(See fdisk(8).)

 

[dietmar]

those are only warnings. partitioning is ok anyways - creating the volume group fails.

So is there any warning/error convercing vgcreate?

[dietmar]

Wait. What does:

6 750GB RAID 5

mean? How large is your disk? We are currently limited to 2TB.

its 6 HDD and every disk i 750GB in raid 5

 

[dietmar]

That is about 3,7TB, which is too large for MBR based system. You need to create a smaller raid device (2TB is the limit)

I configure the RAID 5 like this.

First logical disk 100 GB
Second logical disk 3 TB

The logical disk are using a small part of the RAID 5

First logical disk

( HDD1 HDD2 HDD3 HDD4 HDD5 HDD6 ) = RAID 5
( 16GB 16GB 16GB 16GB 16GB 16GB ) = First Logical disk 100gb

When at chose the 100GB disk under the installation ( The proxmox finds the disk ) I get the same error.
.

EDIT: I did manage to install proxmox on one disk ( no RAID ) but I need to make this work on RAID 5

I manage to install proxmox on the server. I have configured the server like this:

100GB

1.8TB

1.8TB

I installed proxmox on the 100GB but I cant see the other disks!

Currently Proxmox VE supports one local storage for VM´s. So for the moment and based on your hardware you get the best if you configure a RAID10 with 4 disks and a hot spare (so you got 1,5 TB for Proxmox VE).

In future versions (See roadmap) Proxmox VE will have a flexible storage pools so you can add additional storages (local and remote).

You need to partition and mount that manually.
