# Organiser votre pool avec un sous volume ZFS
zfs create rpool/vz
zfs list

#re-définir le point de montage local par défaut pour Proxmox :

# lxc setting

For version >= 6.5.x the simple approach is edit /etc/pve/nodes/ns316107/lxc/VMID.conf then enter this line:

```
lxc.prlimit.nofile: 150000
```

Then .. restart the CT.
