尝试格式化这个/dev/mapper/nvmeVg-var未安装的 LV。见findmnt下文。
mkfs.ext3 /dev/mapper/nvmeVg-var
mke2fs 1.45.6 (20-Mar-2020)
/dev/mapper/nvmeVg-var contains a ext4 file system
last mounted on /var on Mon Oct 11 23:18:35 2021
Proceed anyway? (y,N) y
/dev/mapper/nvmeVg-var is apparently in use by the system; will not make a filesystem here!

我晚上拔掉了所有电源，安装了备用电池，今天早上一切正常sudo mkfs.ext4 /dev/mapper/nvmeVg-var
