[SOLVED] Recover data Debian Machine not booting

[simoberny]

Hi, today i was working on a VM based on debian and i installed systemd as a sostitute of sysvinit. Rebooting the machine result in the VM not booting with error "TASK ERROR: command 'systemctl start pve-container@1113' failed: exit code 1".

Unfortunately the machine (for a strange reason) had not backup and snapshot configured.
Since in the machine there was some important file, there is a way to recover it somehow?
There is no something like grub to send command or the possibility to read the vm disk from another vm linux machine?

Thanks in advance

Is this a VM or a Container? Looking at the error message you sent, it looks like a container to me.

If you only need a file from inside the container, you can try running:

pct mount CTID

where CTID is the ID of the Container (should be 1113 in your case).

This will mount the rootfs of the container and tell you where it's mounted. From there, you can simply cd inside and copy whatever files you need.

depending on the debian version it might be incompatible to run systemd inside a container - e.g. Debian Jessie+unprivileged containers - AFAIR.

Regarding the data-recovery:
You can try to simply mount the container - and check the contents - `pct mount 1113` - check out the `pct` manpage

If you want to check out the error - start the container in foreground and gather some debugging logs: https://pve.proxmox.com/pve-docs/chapter-pct.html#_obtaining_debugging_logs


hope this helps

Yeah sorry, i meant a container.

And yes with your suggestion, mounting the container, i'm able to recover everything. Amazing! This is exactly what i needed
Thanks a lot for the help
