need cluster suggestions

[copymaster]

Hi,

i want to test Proxmox in a cluster environment.

1 master (Dual Xeon Nehalem, 12 GB Ram, 200 GB with 3xraptor Sata hhd raid 5)
3 Nodes (Dual Xeon Nehalem, 12 Gb Ram, 2 TB with 3x 1TB Sata in Raid 5)

A SAN (Netapp) is also in Staff. But if ISCSI, i have to share with the network, means no dedicated iscsi network! ISCSI traffic would be shared with normal network traffic. CIFS and NFS are also possible.

i want to have 2-3 Windows Terminalserver on each Server and 1-2 Linux Servers.

What for a setup would you suggest?
I'd like to have the snapshot feature of LVM, if possible, an automated Backup strategy and i want to have the ability to migrate a VM fast from one Host to another.

How should i install such a cluster?

I already tried to install the master and a node, but on the node theres only "local storage" which is no LVM. How do i have to configure such a setup?


Thanx in advance.

by th eway: is there a german forum?

there is no german forum yet, sorry.

if you want fast migration, you need SAN or DRBD (but here only a two node cluster is possible).

as you have more 4 server and you want to live migrate you need an extra SAN. if you want LVM, you need ISCSI or FC. but you posted that you have no extra storage network which is not good. so you can work with vlan, but this is more difficult and has also negative impacts.

if you use NFS you do have live migration but no LVM snapshots. so what is best for you? I suggest you go for iscsi (and LVM on top). but you should go for an extra storage network in this case.

or try the DRBD way! fyi, we can offer commercial support for DRBD if you need it (also 24/7, also in German as the DRBD team is Austrian, too)

Thank you.
Well i have a gigabit switch laying around somewhere, so an extra iscsi network should be possible....

could you please give a few tips or howto's for building this iscsi/LVM thing with my config?

I meant lvm snapshots for making "backups" from the vm's.

For virtual disks I suggest this:
See http://pve.proxmox.com/wiki/Storage_Model#Use_iSCSI_LUN_for_LVM_base

For backup storage, go for a NFS share:
