挂载

root@pve:/mnt# mkdir /mnt/vmdata
root@pve:/mnt# mount /dev/nvme1n1p1 /mnt/vmdata

设置开机自动挂载

root@pve:/mnt# nano /etc/fstab

在文件末尾添加

/dev/nvme1n1p1 /mnt/vmdata ext4 defaults 0 2
# 最后两个参数：
# dump 备份标志，0 表示不使用 dump 备份工具（很少用）
# fsck 检查顺序，0 表示不开机检查，1 表示先检查（通常给根分区），2 表示比根分区晚检查

/dev/nvme1n1p1 这种命名在系统重启后可能会变化（尤其是有多块 NVMe 硬盘时，顺序变动就会导致识别错乱）。更推荐用 UUID= 或 PARTUUID= 来指定分区。

查看 UUID

# etc/fstab 示例
UUID=xxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx /mnt/vmdata ext4 defaults 0 2

修改后重启可能需要一段初始化时间
