Help deleted cache now Openhab doesn't startup

apskinner · July 12, 2017, 2:54pm

I had some strange leftovers from adding and removing bindings, adding and removing items through Paper UI that wouldn’t go away etc so looking through some threads I thought I would clear the temp and cache files

sudo rm --recursive /var/lib/openhab2/cache/*
sudo rm --recursive /var/lib/openhab2/tmp/*

Now openhab won’t start any more. I can’t access via :8080 (site can’t be reached)
I can’t open a karaf console ssh: "connect to host localhost port 8101: Connection refused"
And nothing is coming up in the events.log (clearly because OH isn’t starting)

I tried manually restarting the service, rebooting multiple times, and eventually reinstalled the latest stable version from openhabian-config (same version I was running)

What log do people need to see to help me here I’m lost

try to execute start_debug to see if something useful comes up in the console and/or in the openhab.log:

sudo systemctl stop openhab2
cd /usr/share/openhab2/
sudo ./start_debug.sh

sudo mkdir /var/lib/openhab2/tmp
sudo chown -R openhab:openhab /var/lib/openhab2/tmp

you should be ready after this

apskinner · July 12, 2017, 3:12pm

And then restart openhab?

Dim · July 12, 2017, 3:13pm

yup

sudo systemctl restart openhab2

note: i think that in openHABian, the username that should be used is: openhabian
if the above doesn’t work, try:

sudo chown -R openhabian:openhab /var/lib/openhab2/tmp

check other folder permissions with:

ls -al /var/lib/openhab2/

Dim · July 12, 2017, 3:17pm

by the way: this command does not remove the tmp directory…
it seems that you wiped it out with another command…

apskinner · July 12, 2017, 3:17pm

Thanks, a whole lot of errors in the logs as it starts but I’ll change the ownership to openhabian (you are right all the other directories are openhabian) then try again, but a lot seem s related to the camera binding,

Before I’ve changed the ownership it has started though, but I’ll change ownership regardless.

I suspect I left off the /* doh!!

Dim · July 12, 2017, 3:18pm

this is expected the first time you start OH2 after nuking cache and tmp (I get this all the time )

https://community-openhab-org.s3-eu-central-1.amazonaws.com/original/2X/1/1f853db20f7139aab8e3ee996fbddacdfdab6488.jpg

no worries… restart OH2 and these messages will (most likely…) go away (after OH2 has repopulated the cache and tmp)

apskinner · July 12, 2017, 3:21pm

Oops after the second rename the group and owner look reversed

reversed the command, I can never remember which is group which is user
sudo chown -R openhab:openhabian /var/lib/openhab2/tmp

Dim · July 12, 2017, 3:25pm

first is user, second is group
(my bad… the correct chown command is the one you used…)
sudo chown -R openhab:openhabian /var/lib/openhab2/tmp

is everything ok now?

apskinner · July 12, 2017, 3:44pm

Minor emergency there, the Razpberry module didn’t power up.
Ok after shutdown and physical power off.

Anyway -
[Service]
EnvironmentFile=/etc/default/openhab2
User=openhab
Group=openhab
WorkingDirectory=/usr/share/openhab2

… and then you withdrew your post

Well I seem to be working so for now thank you very much.

Dim · July 12, 2017, 3:45pm

sorry I realized that you found the answer yourself (from looking at the other dirs within /var/lib/openhab2)
