Description of problem:

Inside a VM, mount a filesystem multiple times:

1. mount | grep vda3
   /dev/vda3 on / type xfs (rw,relatime,seclabel,attr2,inode64,logbufs=8,logbsize=32k,noquota)
   /dev/vda3 on /mnt type xfs (rw,relatime,seclabel,attr2,inode64,logbufs=8,logbsize=32k,noquota)

Notice this is a 100G disk.

1. lsblk
   NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
   vda 252:0 0 100G 0 disk
   ├─vda1 252:1 0 1M 0 part
   ├─vda2 252:2 0 100M 0 part /boot/efi
   └─vda3 252:3 0 99.9G 0 part /mnt
   vdb 252:16 0 1M 0 disk

Now open the console and go to
Virtualization -> Virtual Machines -> xyz -> Overview -> Utilization -> Storage

Wait about 5 minutes

You will see X used out of 200G, its counting vda3 twice due to the multiple mounts of the filesystem.

That is incorrect. The VM has a 100G disk and it should not sum all the available and used spaces for all mountpoints.

Version-Release number of selected component (if applicable):
OCP 4.12.6
CNV 4.12.1

How reproducible:
Always

Steps to Reproduce:
1. Mount the same filesystem twice or more, to different mountpoints
2. Go to Utilization -> Storage

Actual results:

• Incorrect data reported

Expected results:

• Correct utilization reported

Additional info:

• This breaks reporting for Hypershift NodePool VMs, where the filesystems are mounted many times over.
