When installing Proxmox VE 4.1, it fails right at the begining of installation with messages and prompted “unable to create volume group at /usr/bin/proxinstall line 519”.
Error as follow below:

- I resolved this problem by simply changing the RAID option to 0 and the file system to ZFS to overide the existing block (volume).
- After this i reinstalled, haven reverted back to the existing file system and reinstalled Proxmox and it worked.
