Enter the command fdisk-l to view the hard disk and find the data disk to be mounted here: / dev/xvde: 536.9 GB

[root@localhost ~] # fdisk-l

Disk / dev/xvde: 536.9 GB, 536870912000 bytes, 1048576000 sectors

I size (minimum/optimal): 512 bytes / 512 bytes

-- format the disk

Using the data disk for the first time, format the data disk with the command mkfs.xfs / dev/vdb before mounting, here in xfs format

If you need to change to another file system format (such as ext4, etc.), you can change it to the corresponding format. If you use ext4, it is mkfs.ext4 / dev/vdb.
