Again, this assumes the same size or larger drive. See the ~~Extra~~ Section at the end for information on expanding LVs and File Systems AND the appropriate time to do those resizings.

Of course all this will be scripted in the future. So basically Acronis for Linux.

=== Resizing Drives ===

Use CFDISK to resize a Partition

Line 91:

PARTUUID: sfdisk --disk-id /dev/sda 0x40dae42c (remember, the 0x is sort of a static thing that has to preceed whatever ever value is to be changed, plus the partition number will be tacked onto the end. IE, if one has a PARTUUID Number as 55fa144a-01 and wants to change a PARTUUID number to this, 40dae42c, add 0x, that's a zero, in front of 40dae42c, and the -01 will be tacked onto the end of it when viewing with blkid)

=== Drive Creation and LVMs (Logical Volume Management SYSTEMs) ===

cfdisk

pvcreate /dev/nvme2n1p1

vgcreate VG.NVMEx1.P1 /dev/nvme2n1p1

lvcreate -L 460G -n LV.Storage VG.NVMEx1.P1

mkfs.ext4 -L Storage_NVMEx1 -v /dev/VG.NVMEx1.P1/LV.Storage

pvs, vgs, lvs AND pvdisplay, vgdisplay, lvdisplay
