turnkey containers need privileged CT to work

also when you ran the debug command, it wrote a file in /tmp/lxc-100.log. you should attach that file here, as that has the most verbose information.

I can see that it says mount failed. does not exist, but this is not true.

we will see what's going on in the full debug log.
can you see the disk with fdisk -l or lsblk and similar commands?

has something changed for how to properly pass a block storage device to a container?

we changed some stuff in our mounting API to allow hotplugging, but that shouldn't affect this process

thank you, momentary lapse, CT recreated now to get log

i've reached my limit on trying 'random' ideas. i'm about to start researching downgrading... smh so frustrated this was working before update... :(

Edit: I read also, at some point it was best to mount disk by-id and this did work for me in the past. however, it now seems the only way i'm updating and mounting my ext device to container is by using
Code: 
 pct set 100  --mp0  /dev/sdc1,mp=/mnt/extHDD,backup=0,ro=0
like a charm

not exactly, [SOLVED] but, i'm satisfied with this outcome as long as it holds after reboots etc.
