Can't stop container - lock file does not exist?

[fribse]

Proxmox version 6.4-13

I'm trying to shutdown a container and the shutdown just keeps showing as 'working'.
I also tried a stop, and that tells me it can't lock file /run/lock/lxc/pve-config-106.lock
Looking in that folder, the file doesn't exist.

I tried looking at the processes:

root@pve:~# ps aux | grep 106
root       106  0.0  0.0      0     0 ?        I<   Feb02   0:00 [acpi_thermal_pm]

I can see that others mention NFS mounts, it does have nfs mounts from a NAS, but I'm not sure how to unmount them, as the console is just blank.

hi,

firstly try to stop the "Shutdown" task (double click it in the tasklog then select stop).

I can see that others mention NFS mounts, it does have nfs mounts from a NAS, but I'm not sure how to unmount them, as the console is just blank.

could you post the container config from /etc/pve/lxc/CTID.conf (CTID = 106 for you)

if you just want to stop the container you can try:
1. pct stop 106 --skiplock (should skip the locking part)
2. if that doesn't work, you can just kill the process /usr/bin/lxc-start -F -n 106 by running kill -9 PID (where PID = 2015 according to your ps aux), but beware that this is basically a forced kill!

Proxmox version 6.4-13

you should upgrade to the latest 7.x when you get a chance [0]

hope this helps!

Hi @oguz


Thanks for getting back to me , the config looks like this:

arch: amd64
cores: 2
features: mount=fuse,nesting=1
hostname: plex
memory: 2048
nameserver: 10.11.14.1
net0: name=eth0,bridge=vmbr0,gw=10.11.14.1,hwaddr=9E:2C:40:B8:F4:B7,ip=10.11.14.9/24,tag=60,type=veth
onboot: 1
ostype: ubuntu
rootfs: LVM2:vm-106-disk-1,size=70G
searchdomain: fribert-iot.local
swap: 4096
lxc.cgroup.devices.allow: c 226:0 rwm
lxc.cgroup.devices.allow: c 226:128 rwm
lxc.cgroup.devices.allow: c 29:0 rwm
lxc.autodev: 1
lxc.hook.autodev: /var/lib/lxc/106/mount_hook.sh
lxc.mount.entry: /dev/fuse dev/fuse none bind,create=file 0 0
lxc.cap.drop:
lxc.cap.drop: mac_override sys_time sys_module sys_rawio

The kill of the process worked, it is down now.
The container is a plex server, so it has ties to the onboard intel graphics card, that's why there are some extra fiddly stuff in the config.

Ahh, yes upgrade, thankyou very much for the link, I hope I can get some time to it during this weekend.
I think I'm going for a reinstall just to make sure that the pve is on one disc, and the vm's are on another (bigger ssd).
