casaos default settings

[frezeen]

i create a casaos LXC with default settings
use 8.2 proxmox LXC device pass for my ext4 disk /dev/sda.
in casaos>storage i add new storage without format it (create button). i have storage successfull green message but storage is not created.

i try privileged too but same result
how can i fix it? i dont want to format my ext4 disk

edit: form LXC shell i can mount /dev/sda1 in casaos /mnt/test and i see data (tested with privileged only)
