One of my container(LXC) was failed to start.
Error :
Job for pve-container@114.service failed because the control process exited with error code.
See “systemctl status pve-container@114.service” and “journalctl -xe” for details.
TASK ERROR: command ‘systemctl start pve-container@114’ failed: exit code 1
From the debug :
lxc-start 114 20181126024829.995 DEBUG lxc_conf – conf.c:run_buffer:338 – Script exec /usr/share/lxc/hooks/lxc-pve-prestart-hook 114 lxc pre-start with output: mount: /dev/loop0: can’t read superblock
This container used external drive as root disk. There were power issues on the storage itself and make the file system corrupted.
To solved this problem i have run :
e2fsck -fyv /mnt/pve/{my-drive-name}/images/114/vm-114-disk-1.raw
Journal checksum error found in /mnt/pve/{my-drive-name}/images/114/vm-114-disk-1.raw
