you miss some important things, did you try to reinstall all the mail stack
yum reinstall nethserver-mail-\*

Even doing the reinstallation nothing has changed.

the service is down it doesn’t surprise me much
in the cockpit the antispam service is enabled
no solution?
yet no :-?
My cristal ball is broken, did you try to reboot your server and trigger
signal-event nethserver-mail-filter-save
give us also the full message to the start of rspamd and redis-rspamd, maybe something has changed
nothing new

[root@srvmail ~]# redis-cli -s /var/run/redis-rspamd/rspamd monitor
Could not connect to Redis at /var/run/redis-rspamd/rspamd: No such file or directory
Check if the folder of the redis socket exists
/var/run/redis-rspamd
What is the permission of this folder
[root@srvmail ~]# ls -al /var/run/redis-rspamd
ls: cannot access /var/run/redis-rspamd: No such file or directory
Ok this is the important hit, make the the folder with vmail permission iirc
Not at home will check my server later

so it is systemd itself that create the runtime directory, the key is to understand why redis-rspamd doesn’t start
what is the output of
/usr/bin/redis-server /etc/redis-rspamd.conf --daemonize no
no output happens, it remains suspended, I don’t get a new shell…

in /var/run/ never see the folder redis-rspamd
this problem will remain a mystery, and I have another server with the same problem…
@loryaegis this is a perfect timing for… check the marks of the servers.
What are the differences, which are the similarities. Of course… excluding the obvious (hostname, ip addres, etc etc) but maybe the two setups/installatins share something.
Same ISP? Same kind of connections between ISP And Nethserver (forwarding included if behind a nat) or CPE setup…
IIUC you did a migration by a backup, then maybe we could reproduce it, could you confirm ?
Yes,
fantastic! we understood the problem, thank you very much @stephdl .
It is a problem of permissions.
chown redis:redis -R /var/lib/redis
systemctl start redis-rspamd
systemctl status redis-rspamd
ll /var/lib/redis/rspamd/
total 12
-rw-r--r-- 1 redis mail 4626 Sep 17 17:10 dump.rdb
Yes my concern was that the /var/lib/redis
folder was set with an ownership to olefy:olefy
How we can prevent this for the next time
Why this ownership has been set by the restoration
cc @davidep
To summarize, redis-rspamd doesn’t want to start because redis
lost the permission to /var/lib/redis
, the owner and the group was olefy
yes exactly, I had this problem on 2 servers always after the restore.
I confirm that on the other server I solved the group permissions change.
Little bug?
