After installed you can join the server to the pool, however you have to make sure that the Linux pack has been installed.

You will receive a message saying different version so the server can not be added it.

If you do not have the linux pack installed , create a USB drive with the Linux Pack ISO, then plug in it to the server.

#mount /dev/sdX1 /mnt

Make sure what /dev/sdX the server assigned to the USB. (you can check that using dmesg)

then do

#cd /mnt
#./install.sh

Done, now you can join the server to the pool.
