vzdump disk

[iruindegi]

Hi,
We have a server with proxmox witch have this storage setup:

• /dev/sda 930.Gb (SSD)
• /dev/sdb 1.82 Tb (raid)

On the storage part of proxmox we can see:

• local => VZDump backup file, ISO image, Container template => 94.37 GiB
• local-lvm => Disk image, Container => 810.25 GiB

So I asume that this local and local-lvm are being stored in /dev/sda.

What we want is to use SSD for machines and the raid (sdb) for backup destination.

- How can I check if the sdb is being used?
- if is not used, I have to partition it and add it to proxmox, right?
- It's good idea to create new VM with freenas and passthrought sdb to mount a shared storage?

thanks in adavance

depends on how it is used, but normally with tools like lsblk, mount, or commands like 'cat /proc/mounts'

yes if you want it for backup storage, there has to be a filesystem on it

- It's good idea to create new VM with freenas and passthrought sdb to mount a shared storage?

i do not know if it is a good idea to just pass through a single device to freenas, but in principle it should work.
what to you want to achieve here? you can do a nfs export also on the pve host for example, or use a virtual disk for freenas
