[SOLVED] Unable to start Ubuntu container

[crider17]

Hello -

I lost power today and when I booted back up my Proxmox server (6.3-3) my Ubuntu (18.04) container will not spin up. It had "Config locked (snapshot-delete)" status.

"pct unlock 100" removed the status. However, I still cannot get the container to spin up.

When I run "lxc-start -n 100 --foreground --logfile test.log --logpriority=2"

test.log says:
lxc-start 100 20210319224424.819 ERROR conf - conf.c:run_buffer:314 - Script exited with status 32
lxc-start 100 20210319224424.819 ERROR start - start.c:lxc_init:798 - Failed to run lxc.hook.pre-start for container "100"

lxc-start 100 20210319224425.838 ERROR lxc_start - tools/lxc_start.c:main:314 - Additional information can be obtained by setting the --logfile and --logpriority options

I'm a bit over my head at this point. Any idea how I can fix this?

Thanks!

Hi,
Take a look at Cannot remove Snapshot ( VM is locked (snapshot-delete) )

 

[frkb]

Again,
I had the same concerns after backup crash.
Removed whole entry in .conf file but snapshot remain in zfs.
Is it safe to remove it with zfs destroy rpool/data/subvol-111-disk-1@vzdump ?

Hi - seems to be working now. The system seemed to be choking on trying to mount my USB drive:
lxc-start 100 20210320013108.916 DEBUG conf - conf.c:run_buffer:303 - Script exec /usr/share/lxc/hooks/lxc-pve-prestart-hook 100 lxc pre-start produced output: mount: /var/lib/lxc/.pve-staged-mounts/mp2: special device /dev/sdc1 does not exist.

So, I unplugged the drive rebooted. It booted right up. I've since reset it and plugged it back in and it seems to be fine.

Thanks.

Got same errors, with a container having /etc directory moved away... seems like /etc directory is mandatory for lxc.
