刪除某個vm, 但是失敗

root@pve:/dev/zvol/zdata# zfs destroy zdata/vm-103-disk-0
 cannot destroy 'zdata/vm-103-disk-0': dataset is busy

停用 multipathd 服務, 然後再刪除看看, 結果成功

root@pve:/dev/zvol/zdata# systemctl stop multipathd.service
 Warning: Stopping multipathd.service, but it can still be activated by:
   multipathd.socket
