# installimage e ZFS - Proxmox Hetzner
|
|
|
|
Detalhes de instalacao via installimage e configuracao ZFS.
|
|
|

|
|
|
|
## Template installimage
|
|
|
|
Template base para 2x NVMe 1TB + HDD 16TB:
|
|
|
|
```bash
|
|
DRIVE1 /dev/nvme0n1
|
|
DRIVE2 /dev/nvme1n1
|
|
SWRAID 0
|
|
SWRAIDLEVEL 0
|
|
BOOTLOADER grub
|
|
HOSTNAME HOSTNAME_PLACEHOLDER
|
|
PART /boot ext3 1024M
|
|
PART lvm vg0 all
|
|
|
|
LV vg0 root / ext4 50G
|
|
LV vg0 swap swap swap 16G
|
|
LV vg0 tmp /tmp ext4 10G
|
|
LV vg0 home /home ext4 20G
|
|
|
|
IMAGE /root/images/Debian-bookworm-latest-amd64-base.tar.gz
|
|
```
|
|
|
|
## Executar installimage
|
|
|
|
```bash
|
|
# No Rescue Mode
|
|
installimage
|
|
|
|
# Seleccionar Debian 12 (Bookworm)
|
|
# Copiar template acima
|
|
# Salvar e confirmar
|
|
# Reboot automatico
|
|
```
|
|
|
|
## Conversao para ZFS (Pos-Install)
|
|
|
|
**IMPORTANTE:** installimage nao suporta ZFS directamente. Workflow:
|
|
1. Instalar Debian 12 com LVM (installimage)
|
|
2. Boot em Debian
|
|
3. Instalar ZFS + Proxmox
|
|
4. Migrar para ZFS pool (ou aceitar LVM para root, ZFS para VMs)
|
|
|
|
### Opcao A: ZFS para VMs apenas (RECOMENDADO para Hetzner)
|
|
|
|
```bash
|
|
# Criar ZFS pool em NVMe para VMs
|
|
zpool create -f \
|
|
-o ashift=12 \
|
|
-o compression=lz4 \
|
|
-o atime=off \
|
|
rpool mirror /dev/nvme0n1p3 /dev/nvme1n1p3
|
|
|
|
# Criar datasets
|
|
zfs create rpool/vm-disks
|
|
zfs create rpool/ct-volumes
|
|
```
|
|
|
|
### Opcao B: ZFS root (AVANCADO - requer reinstall manual)
|
|
|
|
- Nao suportado por installimage
|
|
- Requer particionamento manual + debootstrap
|
|
- Consultar: https://pve.proxmox.com/wiki/ZFS_on_Linux
|
|
|
|
**Recomendacao para Cluster Descomplicar:** Opcao A (LVM root, ZFS para VMs)
|

## ZFS Tuning (128GB RAM)
|
|
|
|
### Configurar ARC Limits
|
|
|
|
```bash
|
|
# ARC max 16GB (deixa 110GB para VMs)
|
|
# ARC min 4GB
|
|
echo "options zfs zfs_arc_max=17179869184" >> /etc/modprobe.d/zfs.conf
|
|
echo "options zfs zfs_arc_min=4294967296" >> /etc/modprobe.d/zfs.conf
|
|
|
|
# Aplicar
|
|
update-initramfs -u -k all
|
|
```
|
|
|
|
### Optimizar ZFS para NVMe
|
|
|
|
```bash
|
|
# Verificar ashift (deve ser 12 para NVMe 4K sectors)
|
|
zdb -C rpool | grep ashift
|
|
|
|
# Activar compression LZ4 (se ainda nao)
|
|
zfs set compression=lz4 rpool
|
|
|
|
# Disable atime (performance)
|
|
zfs set atime=off rpool
|
|
|
|
# Snapshot visibility
|
|
zfs set snapdir=hidden rpool
|
|
```
|
|
|
|
### Criar ZFS Datasets para PBS (se HDD 16TB)
|
|
|
|
```bash
|
|
# Dataset para PBS datastore
|
|
zfs create rpool/pbs-datastore
|
|
zfs set mountpoint=/mnt/pbs-datastore rpool/pbs-datastore
|
|
zfs set compression=lz4 rpool/pbs-datastore
|
|
zfs set dedup=off rpool/pbs-datastore
|
|
```
