Hi everybody,

I am facing problems starting all of our containers on a pve node after dist-upgrade and reboot.
All containers fail to start, VMs are coming up without problems.
It seems to boil down to a lxcfs / FUSE problem -- full messages attached.

Starting on console reveals:

# pct start 100
__safe_mount_beneath_at: 1106 Function not implemented - Failed to open 51(dev)
run_buffer: 314 Script exited with status 1
lxc_setup: 3388 Failed to run mount hooks
do_start: 1218 Failed to setup container "100"
__sync_wait: 36 An error occurred in another process (expected sequence number 5)
__lxc_start: 1999 Failed to spawn container "100"
startup for container '100' failed


So I am running out of ideas what the root cause of the problem could be and how to circumvent it.

Any help appreciated,
Matthias
