Hi,

One of my four containers refuses to restart after a recent power outage. I'd be grateful of steps I can take to try to resolve it.

I've tried issuing the command:
Code:
lxc-start -n 115 -F -lDEBUG -o temp/lxc-115-2.log:

Here's the output at the command line
Code:
lxc-start: 115: conf.c: run_buffer: 323 Script exited with status 1
lxc-start: 115: start.c: lxc_init: 804 Failed to run lxc.hook.pre-start for container "115"
lxc-start: 115: start.c: __lxc_start: 1903 Failed to initialize container "115"
lxc-start: 115: tools/lxc_start.c: main: 308 The container failed to start
lxc-start: 115: tools/lxc_start.c: main: 314 Additional information can be obtained by setting the --logfile and --logpriority options

And
Here's the resulting log file:
Code:

please post the output of `pveversion -v`
if possible also attach the complete debug-logfile of the containerstart (some information seems to be cut-off)

how do you try to restart the container? (executing `reboot` inside the container, `pct reboot 115`? )


Thanks!
 
Thanks for the fast response.

The container used to boot at startup of the host. I've tried to start it from the GUI by selecting the container and clicking start at the top of the page. And I've tried pct start 115 from the command line of the host.

I can't execute reboot at the moment because I can't get it to start. For clarification - I suspect (but cant' be sure) that there was a power failure last time it was running and so it didn't get gracefully shut down.

But all these logs are from using the lxc-start command.

Attached is the debug log file

There have been a few updates to your current state of packages - please upgrade and try reproducing the issue with the latest version (after a reboot)
 
Unfortunately it looks like the problem persists after apt full-upgrade and reboot of host.

Thanks for the complete log - this explains it:
Script exec /usr/share/lxc/hooks/lxc-pve-prestart-hook 115 lxc pre-start produced output: unable to open file '/fastboot.tmp.11249' - Disk quota exceeded

seems your container's root-filesystem is over quota (meaning it has no free space left) -> increase the container's rootfs size - boot it and then try to free up some space inside

I hope this helps!
