I cannot start a container after a power loss.

This is the error I get when starting the container in the front:
root@pve:~# lxc-start -o lxc-start.log -lDEBUG -F -n 112 lxc-start: 112: conf.c: run_buffer: 352 Script exited with status 2 lxc-start: 112: start.c: lxc_init: 897 Failed to run lxc.hook.pre-start for container "112" lxc-start: 112: start.c: __lxc_start: 2032 Failed to initialize container "112" Segmentation fault

My Container Config:
arch: amd64 cores: 2 hostname: Radarr memory: 2048 mp0: /RAIDZ_1/shared,mp=/shared nameserver: 9.9.9.9 net0: name=eth0,bridge=vmbr0,firewall=1,gw=192.168.2.33,hwaddr=12:D9:A8:99:0B:98,ip=192.168.2.32/24,type=veth ostype: debian rootfs: RAIDZ_1:subvol-112-disk-0,size=128G searchdomain: 1.1.1.1 swap: 2048 #lxc.cgroup.devices.allow: c 10:200 rwm #lxc.hook.autodev: sh -c "modprobe tun; cd ${LXC_ROOTFS_MOUNT}/dev; mkdir net; mknod net/tun c 10 200; chmod 0666 net/tun"

Also the Containers which cannot be started also have access to the tun device as well as to a host directory.

Can someone help me?
 
Hi,

if you run LXC in debug mode the debug log would be helpful.
please send the lxc-start.log
 
Of course:

hi,

Code:
lxc-start 112 20200127211509.514 DEBUG    conf - conf.c:run_buffer:340 - Script exec /usr/share/lxc/hooks/lxc-pve-prestart-hook 112 lxc pre-start produced output: unable to detect OS distribution

your rootfs is probably not mounted (your subvol).

check if the zfs pool is mounted.

also see this post[0]

Nope, the subvolume is already mounted... tried that first :/
root@pve:~# zfs mount -O RAIDZ_1/subvol-112-disk-0
cannot mount 'RAIDZ_1/subvol-112-disk-0': filesystem already mounted

Also after doing what you advised in the post you linked the situation sadly did not change:

are you able to mount the container with pct mount CTID? do you see /etc/debian_version in it?

does the container start if you disable the mp0?

since it's a power loss it's hard to tell if there was any damage done to the disk. that can possibly cause corruption. it'd be good to check the disk health with smartmontools and also the zpool health
 
I can mount the subvolume
root@pve:~# pct mount 112
mounted CT 112 in '/var/lib/lxc/112/rootfs'

After commenting out mp0 and trying to start the container I still get the same error.

Also the short smartctl tests completed successfully and do not show any errors. Also no errors on zfs side
 
can you rerun the debug command with the mp commented?
 
Yes, still getting the same error :/

can you post the new debug log as well please
 
Sorry, I first did not find it as I had forgotten that I saved it in a different place..
