[PVE-User] Access disk space from multiple VMs. Is that possible?

[Tom H. Lautenbacher]

Hello Proxmox users,

is it possible to have disk space on a Proxmox server that is accessible 
from multiple VMs?

Here is an example of what I want to do:

1 Server, having a 8-disk-RAID6 on a 3ware 9650SE-8LPML controller. On 
this RAID volume lives Proxmox and:
- "Diskspace A" with some terrabyte of diskspace
- VM1: Samba Fileserver (not holding any own data but serving the data 
on "Diskspace A")
- VM2: FTP Server (not holding any own data but serving the data on 
"Diskspace A")
- VM3: HTTP Server (not holding any own data but serving the data on 
"Diskspace A")

All three VMs should have full read/write access to "Diskspace A" and be 
able to access "Diskspace A" simultaneously without interfering each other.

- Is this possible?
- Are there any limitations?
- is this a good thing to do
- how would I do it?

I am glad for any peace of information, help, hints, etc..

Thank you
Tom
