Storage
| lxc storage create nome dir source=/dev/lxd | dir oppure ZFS |
| lxc storage list | |
|
Creare ed aggiungere secondo volume ad una VM |
| lxc config device override macch_x eth0 | |
| lxc config device set macch_x eth0 ipv4.address <IP> | impostare IP statico – fare restart |
| lxc config edit macch_x | |
Aggiunto ulteriore disco a VM LXD e montaggio come home
– tra < > mettere il nome pensato per i vari oggetti; ad es <pool> io ho usato default.
lxc storage volume create <pool> <vm> <nome-sdb> size=100GiB –type block
lxc config device add <vm> <nome-sdb> disk pool=<pool> source=<nome-sdb>
lxc storage volume delete default <nome-sdb> – da dare manualmente se si cancella la vm
– comandi da dare in console della vm per gestire il disco sdb collegato
fdisk -l
fdisk /dev/sdb
mkfs -t ext4 /dev/sdb se si vuole formattare ext4, io ho usato zfs
blkid -> verifichi e copi UUID della partizione creata
cp /etc/fstab /etc/fstab.original
vim /etc/fstab
—> aggiungere UUID=<uuidverificataconcomandosopra> /home ext4 defaults 0 2
reboot
df -h —-> x verifcare
lxc network info lxdbr0
lxc network edit lxdbr0 —-> in formato yaml visualizzi valori delle key; per modificarlo usare
lxc network set lxdbr0 <key> <value>
<key> esempi: https://linuxcontainers.org/lxd/docs/master/networks/
ipv4.address 192.168.200.x
ipv4.dhcp true (ho provato false ma non mi da accesso ad alcuni container)
