When rebooting Proxmox my nextcloud container fails to start up. When I check the logs I see
Code: 
run_buffer: 322 Script exited with status 2
lxc_init: 844 Failed to run lxc.hook.pre-start for container "105"
__lxc_start: 2027 Failed to initialize container "105"
TASK ERROR: startup for container '105' failed

Here's my container settings:
1691441533148.png

First I thought it was probably because the NFS share was not mounted yet (nextcloud lxc uses the nfs share to store data) but then I noticed that all my other containers like transmission, shinobi etc which also require mounts to nfs shares start up without any issue. All my containers are set to order=any with no startup delay defined on any of them.
Logging into Proxmox UI and then manually starting the nextcloud container works without a problem.

I do remember that I did NOT have this issue previously but I also don't have a timeline as to when my nextcloud decided to stop starting up on boot. Can someone provide any pointer on how to fix this?
 
Any pointers on this please? Now I have 3 containers that fail to start -- nextcloud, shinobi & jellyfin. :(

I looked into the Start/Stop Order but the containers do not depend on each other so I am not sure how that will help.

But the container starts up without a problem when manually starting up so I don't see any errors even when issuing a command line start. It's only the autostart up on boot that fails.

Sounds like you need a systemd dependency to make sure your storage is active before starting containers (or pve-guests). You are not the first but I don't remember the details; hopefully this give you something to search this forum for.
