[SOLVED] LXC not boot after create mount point

[eneesgur]

Hi everyone,

I use Proxmox 6.1. I have an Alpine LXC Container it's id 103. I wanted to create a mount point to mount the container. And i followed the steps;

# pvesh create /nodes/proxmox1/storage/local/content --filename vm-103-disk-1.raw --size 1G --vmid 103
Formatting '/var/lib/vz/images/103/vm-103-disk-1.raw', fmt=raw size=1073741824
local:103/vm-103-disk-1.raw
# pct set 103 --mp0 local:103/vm-103-disk-1.raw,mp=/app,size=1G
# pct status 103
status: stopped
# pct start 103
Job for pve-container@103.service failed because the control process exited with error code.
See "systemctl status pve-container@103.service" and "journalctl -xe" for details.
command 'systemctl start pve-container@103' failed: exit code 1
# pct config 103
arch: amd64
cores: 2
cpulimit: 0

hostname: API-Test
memory: 512
mp0: local:103/vm-103-disk-1.raw,mp=/app,size=1G
net0: name=eth0,bridge=vmbr0,firewall=1,gw=10.10.10.1,hwaddr=D6:F4:DA:66:06:CC,ip=10.10.10.128/24,type=veth
ostype: alpine
rootfs: local:103/vm-103-disk-0.raw,size=1G
swap: 512

and i have removed the "mp0" then starting the container boot successfully.

journalctl -xe output;

I want to create automatically container via API but mount point didn't work. i have tried via web ui, it's working.

hi,

your syntax with pct set is wrong.

try like this: pct set CTID --mp0 STORAGENAME:SIZE,mp=/path/you/want

Thank you, it works.

But i cannot see that usage in API viewer. https://pve.proxmox.com/pve-docs/api-viewer/index.html Path: /nodes/{node}/lxc

Thank you again.

[oguz]

the STORAGENAME:SIZE is a special syntax for creating a new volume and then mounting it (it replaces the volume parameter)
