Where is my disk space?

[hinhthoi]

I have a server with 2x1TB hard disk. After installation of proxmox 4.4 using the proxmox iso image, I got the following disk space information


root@pve:~# df -h
Filesystem Size Used Avail Use% Mounted on
udev 10M 0 10M 0% /dev
tmpfs 6.3G 18M 6.3G 1% /run
/dev/dm-0 95G 8.8G 81G 10% /
tmpfs 16G 104M 16G 1% /dev/shm
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 16G 0 16G 0% /sys/fs/cgroup
/dev/fuse 30M 20K 30M 1% /etc/pve


So I'd like to ask whether this is normal? How to show all space available? Or is this a bug?

Thank you for any help!

We use LVM. To get a quick overview use

# vgs

So, that is the normal output of "df -h" command, isn't it?

When using vgs, I got

root@pve:~# vgs
VG #PV #LV #SN Attr VSize VFree
pve 1 23 0 wz--n- 931.26g 15.79g

How come the free space left is only 15.79G? Do I have some misunderstanding here?

Thank you very much!

I guess you should read a general introduction for LVM ...
