Additional Prometeus disk volumes?
When I create some Prometeus instances I notice that 2 volumes are created for each instance eg ROOT-1234 has an accompanying DATA-1234, but it the DATA-1234 does not show in the VM.
Does the DATA-xxxx need to be separately mounted to be available to the ROOT-xxxx?
I don't see any sign of how that is done. To be honest as I think I have done it before and forgotten how it works.
Is the DATA-xxxx volume appearing because I needlessly add additonal storage when I am creating the instance?

What does:
fdisk -l
show?
It will probably show the second disk as /dev/vdb
Yep that's quite easy to end up doing that, see if it's attached to the VM, if it Is then you can either use it or detach it, once detached you can delete it.
You can run with with just the Root volume (providing it's large enough) no problem.
