Chapter 16. Mounting file systems

Procedure

1. To attach a certain file system, use the mount utility:

   # mount device mount-point

   Example 16.2. Mounting an XFS file system

   For example, to mount a local XFS file system identified by UUID:

   # mount UUID=ea74bbec-536d-490c-b8d9-5b40bbd7545b /mnt/data

2. If mount cannot recognize the file system type automatically, specify it using the --types option:

   # mount --types type device mount-point

   Example 16.3. Mounting an NFS file system

   For example, to mount a remote NFS file system:

   # mount --types nfs4 host:/remote-export /mnt/nfs

Procedure

1. To change the directory in which a file system is mounted:

   # mount --move old-directory new-directory

   Example 16.4. Moving a home file system

   For example, to move the file system mounted in the /mnt/userdirs/ directory to the /home/ mount point:

   # mount --move /mnt/userdirs /home

2. Verify that the file system has been moved as expected:

   $ findmnt
   $ ls old-directory
   $ ls new-directory

Procedure

1. Try unmounting the file system using either of the following commands:

   • By mount point:

     # umount mount-point

   • By device:

     # umount device

   If the command fails with an error similar to the following, it means that the file system is in use because of a process is using resources on it:

   umount: /run/media/user/FlashDrive: target is busy.

2. If the file system is in use, use the fuser utility to determine which processes are accessing it. For example:

   $ fuser --mount /run/media/user/FlashDrive
   
   /run/media/user/FlashDrive: 18351

   Afterwards, stop the processes using the file system and try unmounting it again.

Procedure

1. Log in to the RHEL 9 web console.

   For details, see Logging in to the web console.

2. Click the Storage tab.
3. In the Storage table, select a volume from which you want to delete the partition.
4. In the GPT partitions section, click the menu button, ⋮ next to the partition whose file system you want to mount or unmount.
5. Click Mount or Unmount.
