How can I create one logical volume over two disks using LVM?
You should have a look at this detailed answer. Create a physical volume on the first hard drive, and another physical volume on the second hard drive. Create a new volume group, assigning both physical volumes to it. Create a new logical volume in that volume group. Create a new ext3 filesystem in that logical volume.
How to merge multiple hard drives in Linux?
I am a programmer not a system administrator. Use LVM (Logical Volume Management) on Linux.

Docker). However, overlayfs has some limitations compared to a normal filesystem. mergerfs uses FUSE so can run in user space and acts like a normal filesystem. Of these choices I would recommend mergerfs or overlayfs depending on your needs.
Is it safe to combine two hard drives into one partition?
Simply combining the two as a single large partition without any means of back-up of the data, is not a good idea. The data will be interleaved across both disks, and if any part of either disk goes bad, you could end up losing all 6TB of data (assuming you had that much data), rather than only half at most.
What do you need to know about LVM?
LVM (Logical Volume Management) – Combine Physical Drives and more! LVM (Logical Volume Management) – Combine Physical Drives and more! LVM is a very cool volume management tool. It can be used for a variety of tasks and this guide explains all the things LVM can do.
How to combine two logical volumes that reside?
One of those lines will tell the system to mount the /home partition. Put a # before it. Press Ctrl-O, Enter, Ctrl-X. Now you can reboot. (Hypothetically, if you were to forget to edit fstab like I did, the command to mount your root partition is mount -n -o remount -t ext2 /dev/vg_xxxxxxxx/lv_root /)
How to merge two volume groups ( VGS ) into one?
1. The logical volumes in the VG must be unique. They can be renamed before being moved (merged) if needed. 2. The PV extent size must be the same for both volume groups We can merge the VGs vg01 and vg02 into one single VG vg01. So, in other words, we want to get rid of VG vg02 without losing any data inside it.
