Combine two volume groups

Volume 2 = 10 TB
Volume 3 = 10 TB
How to combine all these volumes to a single group or volume or logical drive to use 30 TB and acts as a single drive.

You're only options on Linux are:
Use a logical volume manager (LVM): https://linuxhandbook.com/lvm-guide/ (skip the section entitled "Lab preparation for hands-on"); or
Use a filesystem that supports what you want to do (like ZoL -- ZFS on Linux -- or btrfs).
Both of ZoL and btrfs work well and are supported on a number of different distros (despite the fact that Linus throws a tantrum every time someone mentions them). The problem is that, once you implement them (or lvm2 -- the standard Linux volume manager), Linode can't deal with them -- some features of the Linode API (those dealing with disc volumes) and backups stop working…as they all depend on ext4.
