[SOLVED] Change Partitioning after fresh install

[Belfaigore]

Hi everyone,

I just make a fresh install of Proxmox from Proxmox 8.1 ISO during installation I setup disk as below :



But this partitioning doesn't suit me; I'd like to implement the one below :



Can I do it after installation throw Proxmox ISO, or do I have to install Proxmox from Debian (during Debian installation, I can use the partion tools) ?
I try to rename LV and VG ( and update Grub paths) ; but I observe, linux initialisation is more slower (from 5s to more than 30s) do you know if some other path need to be updated ?

I try (with GParted) to reduced EFI System wich is in FAT32, but GParted want to convert to FAT16 (FAT32 don't allow partition less than 1Go ?) ; do you know if ther any issu doing this ?

I try to use Proxmox administration interface to setup LVM / LVM-Thin but I can't select drive ; dropdown list is always empty.

I would like to store my CTs an VMs as LV inside lv_vm instead of files into /var/lib/vz.

Thank you for your help, please execuze my syntax, I'm french user.

Ok so I spend all the day but I finaly found all what I want :

A] Renaming volume

# Act as root
su -

# 1. Disable SWAP
swapoff

# 2. Rename Logical Volume
lvrename /dev/pve/swap /dev/pve/lv_swap
lvrename /dev/pve/root /dev/pve/lv_pve
lvrename /dev/pve/data /dev/pve/lv_vz

# 3. Rename Volum Group
vgrename /dev/pve /dev/vg_nvme

#4. Edit GRUB configuration file (update new path)
nano /boot/grub/grub.cfg
#   -> replace `pve-root` by `vg_nvme-lv_pve`

#5. Edit Filesystem table (update new path)
nano /etc/fstab
#   -> replace `/dev/pve/root` by /dev/vg_nvme/lv_pve
#   -> replace `/dev/pve/swap` by /dev/vg_nvme/lv_swap

#6. Enable Swap (recreate mapping)
mkswap /dev/vg_nvme/lv_swap
swapon /dev/vg_nvme/lv_swap

#7. All done, you can restart
reboot

## Check
lsblk

B] Rearrange volumes

# 1. Because LVM-Thin cannot be resize (not yet) we gonna remove `lv_vz` and recreate it
lvremove /dev/vg_nvme/lv_vz
# We recreate LVM-ThinPool of 350GB with 4GB for metadata (~10%) (we win freespace)
lvcreate -L 300G --thinpool lv_vz --poolmetadatasize 3G vg_nvme

# 2. Create `lv_source` to /var/lib/vz/source
lvcreate -L 20G -n lv_source vg_nvme
mkfs -t ext4 /dev/vg_nvme/lv_source
mkdir /var/lib/vz/source
echo "/dev/vg_nvme/lv_source /var/lib/vz/source ext4 defaults 0 2" >> /etc/fstab
systemctl daemon-reload
mount /var/lib/vz/source

# 3. Create `lv_backup` to /var/lib/vz/backup (it's a backup volume, no execution, etc...)
lvcreate -L 100G -n lv_backup vg_nvme
mkfs -t ext4 /dev/vg_nvme/lv_backup
mkdir /var/lib/vz/backup
echo "echo "/dev/vg_nvme/lv_backup /var/lib/vz/backup ext4 nodev,noexec,nosuid 0 2" >> /etc/fstab
systemctl daemon-reload
mount /var/lib/vz/backup

C] Rearrange/Create storage via Proxmox administration interface and associate content with storage :
- Create storage local-backup, of type Directory, pointed on /var/lib/vz/backup, with content VZDump backup file
- Create storage local-source, of type Directory, pointed on /var/lib/vz/source, with content ISO image, Container template
- Create storage local-vz, of type Thin, pointed on lv_vz, with content Disk Image, Container
- Edit storage local, remove all content (already manage by the other storage), only leave Snippet
