[PVE-User] How to get rid of default thin-provisioned default LV "data"?

[Frank Thommen]

Dear all,

when installing PVE on our servers with 1 TB boot disk, the installer 
creates regular /root and swap LVs (ca. 100 GB in total) and the rest of 
the disk (800 GB) is used for a thin-provisioned LV named "data". 
Personally I don't like thin-provisioning and would like to get rid of 
it and have a "regular" LV instead.  However I couldn't find a way to 
achieve this through the gui (PVE 6.1-3).

Did I miss some gui functionality or is it ok to remove the LV with 
regular lvm commands?  Will I break something if I remove it?  No 
VM/container has been installed so far.  The hypervisors are freshly 
installed and they contain additional several internal disks which we 
plan to use for local storage/Ceph.

Cheers
