Check Unmounted Disks in CentOS

In CentOS, you can use the following command to view unmounted disks:

1. Running the command fdisk -l will display all disk partition information. Look for any unmounted disks, as they may not have a mount point.
2. Another method is to use the command lsblk, which will display a tree-like structure of disks and partitions. Unmounted disks will be shown without any mounting point information.
3. When you run the command blkid, it will display the UUID and file system type of all disks and partitions. Unmounted disks may not have a file system type.
4. You can run the command df -h to display the mounted disks and their usage. Unmounted disks will not be shown.
5. Furthermore, you can also check the file /etc/fstab, which keeps a record of all mounted file systems on the system. Disks that are not mounted may not be listed in this file.

By using the above methods, you can view the unmounted disks and further configure and mount them.
