How would I add a second physical hard drive to proxmox

I installed proxmox on a single 250GB hard drive and I would like to add a second identical hard drive to put more VM's on. I already tried once, and didn't get very far. I added it and formatted it as an ext4, but when I went to use the disk, it said only 8GB was available. That's not quite right. So I did some searching and found that I had to make the device ID 8e for a linux lvm. After I did this, it said I had to restart, so I did... and it wouldn't boot!!!

What did I do wrong? And how do I do it right? (I know I could throw in a RAID card and do a RAID 0, but I'd rather not).

Solution 1:

You can either use your new disk to create new storage resources:

• New directory (tree) to store files
  • partition and format your device using your filesystem of choice (ext3/4 and XFS are the most commonly used)
  • mount the FS to, say, /srv (do it manualy with mount command and add it to fstab)
  • create the needed directories with mkdir /srv/{isos,images,templates,backups,containers}
  • create the Proxmox storage resources of type directory in the web UI.
• LVM volume group to store VMs disks "images" as logical volumes:
  • partition your device and set the LVM (8e) flag
  • create a new physical volume with pvcreate /dev/<DEVNAME>
  • create a new volume group with vgcreate <VGNAME> /dev/<DEVNAME>
  • create the Proxmox storage resource of type LVM group in the web UI

Or you can use it to increase size of the default one:

• LVM physical volume to extend the default pve-data LVM logical volume and /var/lib/vz filesystem:
  • partition your device and set the LVM (8e) flag
  • create a new physical volume with pvcreate /dev/<DEVNAME>
  • extend default VG with vgextend pve /dev/<DEVNAME>
  • extend data logical volume with lvextend /dev/mapper/pve-data /dev/<DEVNAME>
  • verify your FS is clean with fsck -nv /dev/mapper/pve-data
  • resize your FS with resize2fs -F /dev/mapper/pve-data
