These days my disks are filling up fast. My current PC holds 7 drives, including 2 NVMe drives. Actually 8 drives as I installed a new HDD today. All of my disks and partitions – with the notable exception of the FAT16 EFI partition for UEFI boot – are using LVM, the Logical Volume Manager.
With the availability of larger drives at reasonable costs, I decided to move some logical volumes (LV) spanning several drives onto one single drive, thus consolidating disks. This one drive will then be mirrored in a RAID-1 configuration for redundancy.
