Hello

I have a problem with Proxmox 5-3-5, i have DELL R740 + DELL MD3820.
I did tests with the configuration of both devices and confused with the configuration of disks.
I would like to perform a clean installation during which all disk settings on the server and dell MD Storage will be cleared. I would like to configure everything from the beginning. Thank you in advance for your help.

PS.
I am new here, so I am sorry if I write not in the place where I need to

You can use the official ISO, which has a graphical installer on it.
https://www.proxmox.com/en/downloads

Or, you can install a clean Debian and follow the instructions here to install Proxmox on top:
https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_Stretch
 
Unfortunately, when installing with ISO settings are and then I have a problem with disks and I would like the installer to also clean data on the external drive DELL MD3820.
 
You can use GParted ISO or similar tools to format/clean your disks.

If you would like to partition manually, I suggest going the Debian install way, where on the Debian Installer there's a partitioning tool.

What kind of problem are you having with the disks exactly?
 
Why don't you just boot into any live CD distro and clean disks from there.
I am partial to linux mint.
Get the is from mint website.
Make a disk or use. Boot of the disk into gui environment. Since it is a live CD all your local disks will be open.

You can use the gparted in gui but it maybe faster from cli.
Open terminal.
Do an lsblk
Identify your disks

Than if small disks under 2tb use gdisk
Else use gdisk to delete and create new gpt table.
Like: gdisk <\dev\seX> and follow the prompts.

After repeating this for all disks you want to clear reboot and install proxmox as usual.
 
There is a packaged tool for cleaning disks called 'wipefs' . I suggest using it on partitions (/dev/sdX1,/dev/sdX2, etc.) individually first and then do the whole disk last (/dev/sdX).

If you do not clean up the partitions first and instead wipe the MBR/GPT tavble first, those partition signatures will be left over causing issues with things like LVM or whatever storage system used them last.
