Boot Disk Wasted Space

[toomanylogins]

I have a clean install of PBS with 2 * 1Tb Mirror raid. I realise HDD are not optimal but this is a small home network and backups are mainly archive.
However the install has used up all space on the first 1Tb mirror as lvm.
This would appear to be a lot of wasted space. Is it possible to resize and create backup directory on the boot volume ?
Thanks
Paul

You can use any folder as a datastore. So why not just create a folder on your 1TB root and use this as a datastore?
