Sharing storage for VMs/guests

[xvegax]

Hi guys,

I have two SSDs running Proxmox and two HDDs connected to it, which are mounted as "hddpool", see below:

user@machine:~$ sudo cat /etc/pve/storage.cfg
dir: local
path /var/lib/vz
content iso,vztmpl,backup
zfspool: local-zfs
pool rpool/data
content rootdir,images
sparse 1
zfspool: hddpool
pool hddpool
content rootdir,images
nodes rakete
dir: backups-ssd
path /var/lib/vz/backup
content backup
maxfiles 4
shared 0
dir: backups-hdd
path /hddpool/backups/
content backup
maxfiles 10
shared 0

Now, I am not sure, how to give access to the VMs/guests properly so they can reach the "hddpool" and store files there.

As far as I know, if I mount "hddpool" to each VM this can end in data corruption, as every VM thinks it is the owner of the HDD and treats it like it.

So, what is the best practise to let the VMs use the HDD pool simultaneously, meaning to read and write files there.

Thank you in advance.

Best regards

One idea might be to set up a network storage.

Thank you for your input, care to elaborate a bit?

Just mount an NFS/CIFS share inside the guest. Make said share at the hypervisor level.
