What happened to my partitions?

Hi there, so the output of lsblk seems very strange on my freshly installed System:

NAME                   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
sda                      8:0    1 117.2G  0 disk 
└─sda1                   8:1    1 117.2G  0 part /run/media/snaens/LINUX_ARCH
zram0                  253:0    0     4G  0 disk [SWAP]
nvme0n1                259:0    0 476.9G  0 disk 
├─nvme0n1p1            259:1    0     1G  0 part /boot
├─nvme0n1p2            259:2    0    47G  0 part 
│ └─ArchinstallVg-home 254:1    0 455.7G  0 lvm  /home
└─nvme0n1p3            259:3    0 428.9G  0 part 
  ├─ArchinstallVg-root 254:0    0    20G  0 lvm  /
  └─ArchinstallVg-home 254:1    0 455.7G  0 lvm  /home

As you can see, the ArchinstallVg-home has a size of 455.7G but nvme0n1p3 which it sits on is smaller than that. Obviously I installed with archinstall, but I did try to manually install before, but the system couldn't boot, so maybe there's some partitions left from that? If so, how do I not repeat the same mistake, as I am pretty sure I have to reinstall the system. Thanks for the help

Re: What happened to my partitions?

Please use [code][/code] tags (you'll see why). Edit your post in this regard.

https://wiki.archlinux.org/title/LVM
ArchinstallVg-home spreads across nvme0n1p2  and nvme0n1p3

The configuration looks a bit messy but is sane.

Obviously I installed with archinstall

I think archinstall still doesn't allow you to repartition anything so you'd have created a raid on the previously existing partitions and then logical volumes on that (instead of just repartitioning the drive)
I'll point out that it's probably not the worst idea to just use the 47G partition as / and the 430G partition as /home

Re: What happened to my partitions?

Obviously I installed with archinstall

wipe the drive with

wipefs --all

and start over from here: https://wiki.archlinux.org/title/Installation_guide
if you encounter issues report back - it'll be easier to fix them this way instead of struggle around with archinstall blackbox voodoo
