[SOLVED] remaining free storage in lvm

[tauceti]

Hi Proxmox users,

I installed Proxmox and was wondering why with the default install there is not allocated free space available...

root@proxmox:~# pvs
PV VG Fmt Attr PSize PFree
/dev/sda3 pve lvm2 a-- <39.50g <4.88g
root@proxmox:~# vgs
VG #PV #LV #SN Attr VSize VFree
pve 1 8 0 wz--n- <39.50g <4.88g


Is this space needed?
Can I use it to extend to my root lvm or the data thin-lvm or should there always be some free space remaining?

Thanks

Look at point "2.3.1. Advanced LVM Configuration Options" of the documentation.
Proxmox will keep some unallocated LVM space because this is used if you want to use features like LVM snapshots.

awesome thanks. I didn't saw it. As I have only the thin data volume then I can use that space.
