@narf27

The OverlayFS involved is still mounted.

So it syncs data. Create a testfile on persistence to see if that gets synced, too.

You can try with this zram-config to start OH and reboot, then check /usr/local/share/zram-config/log/zram-config.log. You should see the sync being executed.

If that does not help then I don’t know what is messed up. I’m out of ideas. It works fine on a fresh install.

[narf27 (Peter)]

enabled OH, created touch /var/lib/openhab2/persistence/somefile and reboot…
and zram-config seems not to be running…

i didn’t do anything else for sure.

[mstormi (Markus Storm)]

you need to systemctl enable zram-config too

[narf27 (Peter)]

hmm. i never disabled that service since re-enabling it this afternoon, disabled only openhab.
tried nonetheless, and ta-da (but… why?!):

i never disabled that service since re-enabling it this afternoon, disabled only openhab.
tried nonetheless, and ta-da

Are you 100% sure?
When disabled, zram-config will not be run to sync to disk on shutdown/reboot so that’s a proper explanation for what we have been seeing.

yes

@mstormi

understood - but i’m really a 100% sure zram was never disabled since ~ 22h ago - at least not by me.

[narf27 (Peter)]

hello again.
just fyi: i started yet another new openhabian config (1.5 image) and didn’t do anything (no restore backup, no mosquitto, didn’t even run openhabian-config) except creating a test.items file with some groups and some generic switches (no bindings) and create a 5switch widget on habpanel.

‘zramctl’ has no output, and openhab:9001 is not reachable (saw this also on another thread).

edit:

Try again with this image.

Try again with this image .

can’t reach openhab, openhab:8080 or openhab:9001 after installation (same with ip address)…

should i enable zram-config and openhab?

edit: is there a service for frontail log, too, or how can i bring that online

[mstormi (Markus Storm)]

@narf27

should i enable zram-config and openhab?

yes in that order, check zramctl inbetween

@narf27

yes systemctl status frontail

@mstormi

openhab and zram-config started on their own after reboot (i had to shut down this “alpha-setup” because i have only one raspi4 and i have constantly switch between “stable” and testing… so reboot means: shutdown yesterday, boot today)

so everything looks good after one reboot, right?

edit: openhabian-config updated itselft. should i “Upgrade System”?

[mstormi (Markus Storm)]

@narf27

so everything looks good after one reboot, right?

Yes.
Now as openHABian works the way it’s supposed to, I’m done with this now

@narf27

edit: openhabian-config updated itselft. should i “Upgrade System”?

yes
you should every now and then anyway, and of course best is when your system is down anyway.

PS: get another Pi. You need it as a spare anyway.

Now as openHABian works the way it’s supposed to, I’m done with this now

yes, openHABian seems to do what it’s supposed to. does openhab-cli backup/restore somehow mess with ZRAM?

@narf27

does openhab-cli backup/restore somehow mess with ZRAM

no it should not. See if that happens without openhab-cli, too.

What are you doing with different SD cards?
You must not run diagnosis on one and change the other, that’s giving absolutely misleading results!

[narf27 (Peter)]

i was planning to shutdown the current alpha-system, write the clean openHABian setup to that card same and start over.
