Do you have many snapshots? What is the output of # systemctl status readynasd # systemctl status apache2 # journalctl -a | grep apache2 | tail -n 20 # journalctl -a | grep readynasd | tail -n 20 # df -h # btrfs fi show # btrfs fi df /data

I don't know how to determine the amount of snapshots and have no clue what would be a lot.

One thing I did notice when trying:

service apache2 restart

[....] Restarting apache2 (via systemctl): apache2.serviceJob failed. See system journal and 'systemctl status' for details.
 failed!

Seems apache is not starting properly.

I did make some changes before to enable SSI, as listed in https://www.readynas.com/forum/viewtopic.php?f=36&t=73204#p408144. But this never presented problems before. The changed files were simply overwriten by the upgrade and I would need to re-apply the changes.
