Backups is like insurance. If something fails or a fuckup happens, we can count on backups. when I went to do some system updates production systems. Went and did a more recent fresh backup, and then I saw it. Really old backups and no new updates. After finding out Backup not being done, I wanted to get to the bottom of it.<\/p>\n\n\n\n

The issue<\/h2>\n\n\n\n

Looking in issue on the 1 other node (pve01) backups where being done. but not the main node (pve02).<\/p>\n\n\n\n

On the main node (pve02), I saw pvesheduler not running.
When trying to start pvesheduler manually with systemctl, command just hangs when trying to start.<\/p>\n\n\n\n

The fix<\/h2>\n\n\n\n

After reading this. I was able to fix it. https:\/\/forum.proxmox.com\/threads\/pvescheduler-is-dead-and-wont-start.120794\/<\/a><\/p>\n\n\n\n

pvesheduler is dependent of pve-guests running. If pve-guests wasn’t able to run the backups would work.<\/p>\n\n\n\n

The pve-guests.service was stuck with a child zombie tread. Killing the parent with SIGKILL made the service unstuck<\/p>\n\n\n\n

Now restarting after unstucking pve-guests pvesheduler.service was able to start, and backups started being taken again.<\/p>\n\n\n\n

What caused it<\/h2>\n\n\n\n

I have no idea, Maybe after a boot.<\/p>\n\n\n\n

@TODO to fix future issues<\/h2>\n\n\n\n

Create a zabbix trigger if it sees zombie processes will sound a trigger.
Make zabbix watch the sensitive processes.
