[PVE-User] Proxmox storage usage

[Rutger Verhoeven]

I recently installed a proxmox server. However the storage usage is
tremendous:

(see attachment)

root at server5:/var/lib/vz# df -h
Filesystem            Size  Used Avail Use% Mounted on
udev                   48G     0   48G   0% /dev

/dev/fuse              30M   16K   30M   1% /etc/pve

  /dev/sdc       lvm2 ---    4.55t   4.55t

  root pve -wi-ao---- 96.00g
  swap pve -wi-ao----  8.00g

The hardware is as follows:
2x 2TB Samsung SSD
2x 5TB Seagate HDD

These are configured as follows:
1x RAID1 => 100GB
1x RAID1 => 500GB
1x RAID1 => 1,37TB
1x RAID 1 => 4,55TB
* RAID = HP Hardware raid

Why am i losing so much storage? It is shown as in use. But nothing is
expect for a vanilla proxmox5 system. I'm at the point of entire reinstall
/ reconfigure now.

Thank you in advance
