Hi.
I have installed Proxmox Ve 2.3 with RAID 1 for system and RAID 6 for storage. Total capacity of storage is 12TB. I create LVM vm_images and mount it to the directory.

11T 159M 11T 1% /storage
Then i added storage from web interface as directory. After that i saw that total capacity of storage is 10.73 Tb and it is normal. But the problem is that 558.15 Gb out of 10.73 Tb are used and i don't understand who uses them.
But! If i add storage as LVM as is described in wiki, i see 10.73 Tb and used 0.
I want to use storage as directory. Could anyone explain why 558.15Gb are used and how to avoid it ???
And second question. Do i understand correctly that i should leave 10-20% of PV unmarked when i use LVM ?
