Slow Bootup

Installation Home Assistant OS
1

So for context, have been running Home Assistant over 2 years in Debian Supervised, but run out of space on my hypervisor.

Had to delete snapshots of the VM to get Home Assistant to recover, took a backup, and decided to reinstall using HAOS.

Now after the backup restore, I’ve noticed that the bootup is quite a bit slower than before.

Timeline Events:

2025-01-02 10:21:26.279 INFO (MainThread) [main] Initializing Supervisor setup

2025-01-02 12:21:26.345 INFO (MainThread) [main] Setting up Supervisor

2025-01-02 12:21:33.562 INFO (MainThread) [supervisor.addons.manager] Phase ‘services’ starting 4 add-ons

Up to this point, things are pretty fast (7 seconds)

…

2025-01-02 12:22:03.773 INFO (MainThread) [supervisor.core] Start Home Assistant Core

2025-01-02 12:27:34.310 INFO (MainThread) [supervisor.addons.manager] Phase ‘application’ starting 5 add-ons

But from starting core & application - 5 minutes

Is this all normal behaviour? Full supervisor log > Home Assistant Log - Pastebin.com

Go to settings → system → repairs, 3 dot menu on the top right, select integration start times. You should be able to see the start times for the individual core entries.

None of the items there add up to 5 minutes.

The issue is more related to home assistant core, as Node-Red container is only started after the core becomes “running” if I look at the supervisor logs

Here is a timeline of the events in your Home Assistant log file:

Probably. You aren’t counting the time to start your OS and VM. In a VM much of your complete system are already running when you started timing your Home Assistant boot.

OTOH- Why does this matter? HAOS is a server and expected to be always-on. I haven’t rebooted my host computer (an Intel NUC i3) in years.

Fair point, but surely a lightweight service like Home Assistant shouldn’t take 5+ minutes to be ready for use?

I’m merely just curious, as my previous supervised installation was lightning fast to boot

So I reverted to downgrading the HA OS to version 13 as a test and now things boot super fast.

2025-01-02 21:13:41.919 INFO (MainThread) [main] Initializing Supervisor setup
…
2025-01-02 21:14:10.029 INFO (MainThread) [supervisor.homeassistant.core] Home Assistant Core state changed to APIState(core_state=‘RUNNING’, offline_db_migration=False)
…
2025-01-02 21:14:40.685 INFO (MainThread) [supervisor.core] Supervisor is up and running

So 1 minute vs previous 5+ minutes
