將 vm213 複寫Replication 到 pve21 (192.168.0.21) 時
出現訊息：

還原備份檔

若原來的 zfs pool 不存在，可以改還原到新的位置：
root@pve5:/var/lib/vz/dump# qmrestore vzdump-qemu-213-2021_02_01-13_34_20.vma.zst 213 --storage local
還原 container：
$ pct restore 202 vzdump-lxc-202-2021_02_18-21_49_48.tar.zst --storage local-zfs
啟動 vm 時一直出現 failed: got timeout
TASK ERROR: start failed: command'/usr/bin/kvm -id 213 -name devp211 -no-shutdown -chardev 'socket,id=qmp,path=/var/run/qemu-server/213.qmp,server,nowait' -mon 'chardev=qmp,mode=control' -chardev 'socket,id=...............e -smbios 'type=1,uuid=640e9277-55a..............................................ddr=0x12,id=net0,bootindex=300' -machine 'type=pc+pve0'' failed: got timeout
結果剛剛 restore 的工作完成後
這個 vm 就正常啟動 ///
真正的原因?!
新安裝的 Proxmox server 沒有 local-zfs
自己新增檔案即可： /etc/pve/storage.cfg
dir: local path /var/lib/vz content iso,vztmpl,backup # default image store on ZFS based installation zfspool: local-zfs pool rpool/data sparse content images,rootdir
