[RESOLVED] LXC not starting

[fakker]

We had a powercut and since then, one of my vms won't start. It's Plex (installed via TTeck github). Other vms have started up fine, but this one just won't boot and I'm way out of my depth trying to figure out why!!

The output from the start task is

run_buffer: 321 Script exited with status 255
lxc_init: 846 Failed to run lxc.hook.pre-start for container "105"
__lxc_start: 2002 Failed to initialize container "105"
TASK ERROR: startup for container '105' failed

Below is the set up ("Homer" is a mounted 1TB drive).

sdc                            8:32   0 931.5G  0 disk
└─sdc1                         8:33   0 931.5G  0 part /mnt/pve/Homer

Any ideas?? I'm stumped. My linux experience is very very limited.

Could you please run pct start 105 --debug in the shell of your Proxmox VE host and post the output here.

It seems like the file system of vm-105-disk-1.raw got corrupted. You can try repairing it by running a file system check.

pct fsck 105 -device mp0

Perfect, thank you! I got some message saying the super block didn't matching something-or-other... then "fixed!"

Brilliant. Thank you!!
