Cannot start a container.

[proxmox_dumb_user]

Hello,
I had a container for owncloud on my proxmox. I added more space to a user. Never had issues with it... now it is just not starting:

These are the logs I am getting:

root@proxmox:~# lxc-start -lDEBUG -o lxc-start.log -F -n 102

This is the container configuration:

rch: amd64
cores: 1
hostname: owncloud
memory: 2048
nameserver: 10.0.0.1
net0: name=eth0,bridge=vmbr0,gw=10.0.0.1,hwaddr=DE:22:E8:25:2D:79,ip=10.0.0.101/24,type=veth
onboot: 1
ostype: ubuntu
rootfs: local-lvm:vm-102-disk-0,size=200G
swap: 512

And my proxmox version is Virtual Environment 6.2-4

Please mark it as fixed. Sorry about that. My local-lvm was full causing the container not to start.
Thank you!
