Can't delete Containers

[axion.joey]

Hey Everyone,

I have two containers that I can't remove from the web interface. When I attempt to delete them I see this error message.

stat(/var/lib/vz/private/386): No such file or directory
Container is currently mounted (umount first)
TASK ERROR: command 'vzctl destroy 386' failed: exit code 41

Here's the information on the proxmox host
proxmox-ve-2.6.32: 3.1-109 (running kernel: 2.6.32-23-pve)
pve-manager: 3.1-3 (running version: 3.1-3/dc0e9b0e)

And this is what I see when I attempt to delete the container from the CLI.
vzctl delete 386
stat(/var/lib/vz/private/386): No such file or directory
Container is currently mounted (umount first)

I rebooted this specific host and every host in the cluster and I'm still seeing the same issue. Any help would be greatly appreciated.

Maybe the container runs on another node (you have a cluster)?

 

[axion.joey]

Thanks for the quick response. I just checked and the containers aren't on any other nodes. Yes we do have 4 servers in the cluster

 

[dietmar]

So the config file is at ls /etc/pve/openvz/386.conf?

try to unmount manually with

# vzctl umount 386

 

[axion.joey]

This is what I receive.

vzctl umount 386
stat(/var/lib/vz/private/386): No such file or directory
Can't umount /var/lib/vz/root/386: Invalid argument

There is no folder in /var/lib/vz/private for the 386 vm. So it looks like the vm's data was successfully deleted. Is it safe to just delete /etc/pve/openvz/386.conf?

 

[dietmar]

I wonder why vzctl thinks it is still mounted? What is the output of

# cat /proc/mounts

But sure, you can delete the config manually.

Here's the output

I would reboot that node in order to get a clean state (seems vzctl is confused somehow).

 

[axion.joey]

Same issue after a reboot.

 

[axion.joey]

I just moved the config files to another location and everything seems to be ok now.
