[BUG Found] unable to remove LXC container

[brosky]

Hi,

System: fresh proxmox 4 install, local storage is 400g SSD and secondary /storage is 12TB HDD

I create a LXC container using the provided ubuntu14 template:

- same situation with CentOS template.
- no issues with VM (the VM is created properly and I can manage the resources)

I've tested in various disk size configurations and only if I specify "1024" as the size it crashes. (1025 or 1000 is fine)
Also, 2048 fails while 2049 works.

As now I have a couple of un-removable LXC containers, please advise to to remove them

 

[sigxcpu]

Remove their config file in /etc/pve/lxc and remove their folder in /storage.

[dietmar]

i have the same problem

Please can you post the container configuration /etc/pve/lxc/<ctid>.conf?

 

[_leo_]

here:

arch: amd64
cpulimit: 1
cpuunits: 1024
hostname: something.mydomain.com
memory: 1024
net0: bridge=vmbr1,gw=XX.XX.XX.XX,hwaddr=XX:XX:XX:XX:XX:XX,ip=XX.XX.XX.XX/24,name=eth0,type=veth
ostype: debian
rootfs: local:101/vm-101-disk-1.raw,size=2T
swap: 1024

 

[wolfgang]

I made a bugfix, will be available in pve-container greater 1.0-8.
current work around make only container with max 1023 G rootfs size.

Ок,

is it ok to delete this lxc with.
rm /etc/pve/lxc/101.conf
and
rm -rf /var/lib/vz/images/101/

?????

 

[wolfgang]

yes this is correct.
