Hi,

we recently installed latest Proxmox version and noticed it saved KVM data to /usr/lib/vz/images instead of creating a new LV for each VM(KVM) like it was doing in version 3.

lvdisplay is empty on Proxmox 5 and all data is saved to /usr/lib/vz/images

is there any way to quickly convert all VMs to LVs instead of /usr/lib/vz/images ?

is proxmox 5 supposed to work that way ?

Update:

I setup a new LV manually(lvcreate) and mounted it to /var/lib/vz, moved backups there and VMs started successfully. Luckily everything started good and working well now.

Is this way new Proxmox 5 is supposed to work or I'm missing something ?
 
Hi,

If you make a default installation without ZFS, the installer creates three LV (root, swap, data).
The data LV is a thin-lvm and will be used as image storage for KVM and Container.
The path /var/lib/vz still exists for backups, container templates, and iso images.
So a normal installation has 2 storages in the GUI local( /var/lib/vz) and local-lvm(LV data).
 
Hi,

FS I used for Debian 9 is ext4 and I had to create data LV manually
lvcreate -L 300G -n data vg1

then mounted it to /var/lib/vz. Is that a good solution or there is a better one? Is there an option to switch so each VM has its own LV like it ws in version 3 ?

Also, I extended data LV but proxmox still shows old size in control panel, while vgdisplay and lvdisplay shows correct sizes. Any insight on that ?

Many thanks for your replies!
 
I believe i did not create new storage from Proxmox GUI, which I was supposed to do. I will delete my manually created LV and try adding a new storage from Proxmox GUI
 
I think I have an idea
1) Reduce current LV size of LV that I created for data and mounted manually to /vz
2) Create a new thin-LVM from Proxmox GUI -> Storages
3) Live migrate VMs from local(default) storage(my customary mounted /vz) to newly created thin-LVM that is setup properly from Proxmox GUI and recognised in Proxmox

Do you think this would work fine ?
