XenServer after installation, resolve system disk 4G size limit cannot upload ISO image larger than 4g (method of mounting new disk)

This method is not stable

We all know that xenserver after installation, no matter how big your plate is, there is only 4 g of space.

So the operation is: New LV volume, customizable size

if the ISO warehouse has been created, simply perform steps 1, 2, 3, 4, 5, 7, 8, 9 to mount the new logical volume drive to the/opt/iso file (the original image disappears )
