This page contains my personal notes on Linux filesystems, partitioning, backups, performance tuning, and related concepts. Warning: these notes are specific to my own non-critical systems and may not be applicable in general use cases.

I'm currently the following configuration on my Dell Precision 5520 notebook computer:

• 256GB NVMe drive
• 512MiB /boot partition as a raw ext4 partition
• 512MiB EFI partition as a raw FAT partition
• the rest of the disk is configured as an LVM PV consuming 92% of the drive
• this currently contains one volume group with two logical volumes, 16GiB for swap (to allow hibernate) and the remaining space is used for /

GNU parted manual: https://www.gnu.org/software/parted/manual/parted.html#Using-Parted-1

parted /dev/nvme0n1
print # check to see what's already on the disk before you do anything else
mklabel gpt
unit MiB # use binary format units when partitioning
mkpart efi fat32 1MiB 513MiB # align the first block
mkpart boot ext4 513MiB 1025MiB
mkpart pv0 ext4 1025MiB 92% # finish the LVM pv at 92% capacity

If this worked you will see something like this when you print the partition table

(parted) print
