Hello Proxmox Community,
I’m seeking help with an LXC container that failed to start and encountered several issues. Here’s a summary of the problem and the steps I’ve taken so far:
Our LXC container (ID: 565) failed to start with the following error message:
Steps Taken:
1. Accessing the Container:
I accessed the container by mounting it and using chroot and found that apt and init were missing. I manually downloaded and installed apt along with its dependencies after several retries.
2. Restoring Basic Functionality:
I managed to reinstall init, and now the container starts, but it’s facing the following issues:
Current Issues:
Is there a better way to recover an LXC container in my situation?
What could have caused this sudden damage, leading to such issues?
Can anyone suggest additional steps to resolve the network interface problems or correct permissions more effectively?
Are there specific logs or files I should check to troubleshoot these issues further?
I’m seeking help with an LXC container that failed to start and encountered several issues. Here’s a summary of the problem and the steps I’ve taken so far:
Our LXC container (ID: 565) failed to start with the following error message:
Code:
sync_wait: 34 An error occurred in another process (expected sequence number 7)
__lxc_start: 2114 Failed to spawn container "565"
TASK ERROR: startup for container '565' failedSteps Taken:
1. Accessing the Container:
I accessed the container by mounting it and using chroot and found that apt and init were missing. I manually downloaded and installed apt along with its dependencies after several retries.
2. Restoring Basic Functionality:
I managed to reinstall init, and now the container starts, but it’s facing the following issues:
- Network Interfaces: The network interfaces are always DOWN on start.
- Permissions: Permissions seem to be incorrect everywhere, and I’ve been trying to fix them using the following approach:
Code:
# /etc: System configuration files
chattr -i /var/lib/lxc/565/rootfs/etc
chown -R 100000:100000 /var/lib/lxc/565/rootfs/etc
chmod -R 755 /var/lib/lxc/565/rootfs/etc
chmod 700 /var/lib/lxc/565/rootfs/etc/cron.d

# /var: Variable data files, logs, and application-specific data
chattr -i /var/lib/lxc/565/rootfs/var

chattr -i /var/lib/lxc/565/rootfs/sbin
chown -R 100000:100000 /var/lib/lxc/565/rootfs/sbin
chmod -R 755 /var/lib/lxc/565/rootfs/sbinCurrent Issues:
- Network Configuration: Network interfaces remain DOWN upon startup. I need guidance on resolving this issue.
- Permissions: Although I’ve made adjustments, the container still exhibits permissions issues. Any advice on additional fixes or checks would be helpful.
- Plesk: I'm unable to install plesk using it's official installer script. This container had it before.
Is there a better way to recover an LXC container in my situation?
What could have caused this sudden damage, leading to such issues?
Can anyone suggest additional steps to resolve the network interface problems or correct permissions more effectively?
Are there specific logs or files I should check to troubleshoot these issues further?
