How can I add new disks to my RAID 0 configuration?

I have a proxmox setup configured with RAID0 (2 x 1T SSD). The RAID0 configuration was done during the proxmox installation.

How can add an extra SSD Disk to this RAID0 setup without reinstalling proxmox?

yep. Basically extend my 2 disk RAID0 configuration to a 3 or 4 disk RAID0 configuration

I guess you know about the risks running a raid0 that if any of those 3-4 disks will fail all data is lost and you don't be protected against bit rot? You usually don't want to use raid0 and use a raid1 or raid10.

To extend the raid0 you would need to add the disks manually via CLI.

1.) connect new new disk of same size and performance characteristics to server
2.) clone the partition table from old disk to new disk using unique IDs
3.) sync the bootloader from old disk partition 2 to new disk partition 2
4.) add partition 3 of the new disk to pool via "zpool add" command:

See paragraph "Changing a failed bootable device" for step 2 and 3 (but skip the "zpool replace" and use "zpool add" instead):
