Error installing Proxmox VE: “unable to create volume group at /usr/bin/proxinstall line 519”

seleLeave a comment

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:
Device boot Start End Blocks Id System
/dev/sda1 * 32 524319 524208 83 Linux
/dev/sda2 524320 293033631 292509312 0e Linux LVM
/dev/sda3 0 – 0 0 Empty
/dev/sda4 0 – 0 0 Empty
Successfully wrote the new partition table
[..]
Physical volume /dev/sda2″ successfully created
A volume group called ‘pve’ already exists
unable to create volume group at /usr/bin/proxinstall line 519
umount: /target/boot: not found
umount: /target/var: not found
umount: /target/tmp: not found
umount: /target/proc: not found
umount: /target: not mounted

Solution

  • 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.

SCP Command
root@HA-Proxy-CL2:/# scp /etc/haproxy/haproxy.cfg root@xx.1×9.41.xx:/etc/haproxy/haproxy.cfg

Now navigate to the other node and view the copied files.
root@ha-proxy-cl1:/etc/haproxy# cp haproxy.cfg haproxy.cfg.bak
