Problem
No users can authenticate or login through any service. No UMC login, no Radius and no Windows client.
Environment
In /var/log/univention/listener.log
you will see:
02.08.20 06:34:05.844 LISTENER ( ERROR ) : Fatal close(/var/lib/univention-directory-listener/notifier_id.tmp): No space left on device
Solution
Free up some space on the filesystem holding /var
.
You might check the backup directory for outdated backups:
32G /var/univention-backup/
root@master:~# rm /var/univention-backup/*2019*
root@master:~# rm /var/univention-backup/samba/*2019*"
root@master:~# du -hs /var/univention-backup/
16G /var/univention-backup/
Step 2 - Restart the services
systemctl stop freeradius
systemctl stop slapd
systemctl stop univention-directory-listener
systemctl start univention-directory-listener
systemctl start slapd
systemctl start freeradius
Step 3 - Reconfigure holding time for backups
To remove such outdated backups after a year automatically set the ucr variable:
ucr set backup/clean/max_age=365
