[SOLVED] possible bug: bindmount into running container no longer works

[n0x0n]

Since 2022, I can bind-mount into a running comtainer (see this post).
While this still worked in January 2024, it's no longer working now.

root@pve:/# pct set 104 -mp1 /media/tmp,mp=/media/usb,replicate=0
400 Parameter verification failed.
mp1: unable to hotplug mp1: failed to move 'mp2' into container hierarchy: Permission denied


pct set <vmid> [OPTIONS]

The GUI displays the following, notice the orange color:


The LXC is a unprivileged container, HA is active.

Manually editing the LXC conf file and adding mp1: /media/tmp,mp=/media/usb,replicate=0 makes the GUI display the following in the usual black:

But in the running LXC, the mountpoint is not mounted.

@fabian: Any idea when the fix will be released?

no ETA, but core packages like pve-container are usually bumped quite frequently.
