enlever le point de montage automatique

vim /etc/fstab

sh zpool create -f -o ashift=12 rpool mirror /dev/sda5 /dev/sdb5 zfs set compression=lz4 rpool zfs set atime=off rpool

systemctl enable zfs-import@rpool.service

zpool list zpool status

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 : zfs set mountpoint=/var/lib/vz rpool/vz

#monter automatiquement les volumes ZFS : zfs mount -a;

zfs get mounted,canmount,mountpoint rpool/vz

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.
