Hi there,

I've got a problem installing Proxmox on my new server:

Hexacore Opteron 4180, 16GB RAM, 4x 2TB WD Caviar Blue as RAID10 with 4TB capa at 3ware 9650SE 4LMPL.

Proxmox recognized all hardware correctly but when it starts installing LVM there is an error telling that at boot-partition there is no msdos-entry, afterwards there is a problem creating an partition in LVM (400000 free but 490000 needed), the partition is told to be 1,8 TB. But I can't imagine that 3,6 TB of space aren't enough ;-)

Anyone any hints?

Thanks, Yves
 
Thanks for your quick reply!

I tried installing Ubuntu Server x64 10.10 instead of Proxmox and Ubuntu did recognize my array correctly using lvm, too. It uses the same kernel 2.6.35 as proxmox does. So this shouldn't be an mbr-problem.

I really would like to try creating two raid-slices with 1,8TB each, but I'm not sure whether the 3ware BIOS of the raid-controller supports to have two raid-sets on the same hdd's.

I will have a look whether this is an option, otherwise I will partition the array with ubuntu the same structure proxmox does, install proxmox on a smaller single 250GB disk (we had already used for testing proxmox) and copy the whole file-structure on the pre-defined array. Let's have a look, whether this would be successful.

I will report again. If there are still any ideas in the meantime, I would be pleased to get it ;-)
 
Ok, I did it! :-) My solution was: install proxmox on a smaller drive (I used a 250GB-drive), start your system with a live-cd (e.g. ubuntu 10.10-server did a good job to me!) and partition your drive manually (create a small boot partition with ext3-fs and two partitions with lvm-fs each not larger than 2TB). Afterwards you have to create the lvm-structure. Create a volume group called some different way then proxmox does, original proxmox uses pve, so at first call it pve2 or something like that. Join the physical drives to the volume group. Afterwards create the logical volumes inside, proxmox uses a swap-volume (dev/pve2/swap) of the size of your RAM, a root-volume (/dev/pve2/root, 58GB on my system) and a data-volume (/dev/pve2/data the whole remaining drive-space). When your done activate the new volume-group und format each partition (ext3 for the small boot partition e.g. /dev/sda1, /dev/pve2/root and /dev/pve2/data, swap for /dev/pve2/swap). Next step is mounting the drives and rsyncing the data from each partition of the small installation-hdd to the corresponding partitions on the new large drive. Shut down your system and disconnect the small hdd. Start the system again with the live-cd and rename the volume-group from pve2 to original proxmox-pve. Mount the partitions under /mnt or /media the way it will be mounted in a working system (/dev/pve/root -> /, /dev/sda1 -> /boot), chroot into the structure and run grub-install. Afterwards reboot without live-cd and Proxmox should be starting!
