Storage Mount Doesn't Work

[john-everden]

I have the following settings:

config.persistent_storage.enabled = true
config.persistent_storage.location = "~/work/pde/data/data.vdi"
config.persistent_storage.size = 15000
config.persistent_storage.mountname = 'persistantdata'
config.persistent_storage.filesystem = 'ext4'
config.persistent_storage.mountpoint = '/webfiles'
config.persistent_storage.volgroupname = 'persistantdata'
config.persistent_storage.variant = 'Fixed'
config.persistent_storage.use_lvm = false

I've also tried without
config.persistent_storage.use_lvm = false

and without
config.persistent_storage.variant = 'Fixed'

Upon creating vagrant instance I see the following disks
vagrant@ubuntu-focal:~$ df -h
Filesystem Size Used Avail Use% Mounted on
udev 474M 0 474M 0% /dev
tmpfs 99M 952K 98M 1% /run

vagrant 954G 118G 837G 13% /vagrant
tmpfs 99M 0 99M 0% /run/user/1000

Notice /webfiles is only a size of 4.8M. Inspecting the actual VDI file I can see it's 15GB. No data I write to this folder survives destorying the vagrant instance.

Was specifically on ubuntu 20.02. The fix was setting config.persistent_storage.diskdevice = '/dev/sdc'
