[SOLVED] Best way to convert lvm to lvm thin

[lacosta]

Hello, what is the best way to convert an existing lvm local storage to lvm thin ? Fresh 4.2 create lvm for template and lvm thin for images. Can i convert local lvm storage without containers ? or use this https://access.redhat.com/documenta...ation/thinly_provisioned_volume_creation.html ? Conversion destroy data, is necessary reformat storage ?

Sorry for bad English

May i ask you... what is the advantage of lvm thin?

Snapshot ? I need this function ...

btw:
If i understand, classic local storage has been moved to pve/root and recreating lv data with parameter -T i get thin pool ?

edit: ok I use this method:
1. remove, move containers (or migrate) from local storage
2. remove /var/lib/vz from fstab
3. lvconvert --type thin-pool pve/data
4. add lvm-thin storage via gui as local-lvm (default proxmox)
5. restore, migrate back containers to local-lvm storage ...
6. now, snapshots working ...

Sorry, but i don't understand you. I use Proxmox since years. Snapshots do always working fine. So what you mean exactly with snapshot?
