I Have single drive for my main proxmox node. It has all VM’s disks. Separate hardware raid has proxmox install.<\/p>\n\n\n\n

Try first in a VM before proceeding. I mainly created this for my self, when I tried this in a VM. Yet to be done in practice in production.<\/p>\n\n\n\n

Plug your new drive in and reboot node.<\/p>\n\n\n\n

Setup disk<\/h2>\n\n\n\n

Go to: Node -> Disks -> ZFS
Make a ZFS pool with that single drive.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Thin provisioning can be enabled in Datacenter -> Storage
Edit the storage and enable Thin provisioning.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Migrate VM’s & CT’s<\/h2>\n\n\n\n

Move all hosts to the new Drive. Probably recommended Delete source is checked.<\/p>\n\n\n\n

VM: Hardware -> Hard Disk
Select the drive you want to move -> Disk Action -> Move Storage<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

CT: Resources -> Root Disk
Select the drive you want to move Volume Action -> Move Storage<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

We can check on the drive we migrated from, is everything is migrated.<\/p>\n\n\n\n

Raid time<\/h2>\n\n\n\n

Go to Node -> Disks -> LVM
Select the Storage you moved everything off of -> More -> Destroy<\/p>\n\n\n\n

Datacenter -> Storage
Select the Storage you moved everything off of -> Remove<\/p>\n\n\n\n

Now SSH, in to your server<\/p>\n\n\n\n

You will need the disk id’s of the zfs storage and the disk we deleted.
Basically # zpool attach <pool> <current-disk-id> <new-disk-id><\/code> To make a mirror raid.
You can get the id of your drive with ls -l \/dev\/disk\/by-id\/<\/code>
Also will need the current disk, can be show with zpoll status <pool><\/code> <\/p>\n\n\n\n
