Hello.
Today, on 25.01.2022, apache, exim4, mariadb stopped working around 8.00 in the morning for unknown reasons. I just restarted these services through the hestia panel, and everything worked. But a lot of data was lost from the database, about 28 GB, fortunately we had backups, but it will take a lot of time to restore such a volume of data. there are no reasons to find in the logs, help us figure it out
I found out that the database is in place. DB was in a different directory unlike /var/lib/mysql. For unknown reasons, the mariadb configs were erased and by default he read the database from the /var/lib/mysql directory, and there the old data stood
Sounds weird, I strongly suggest to check your logs to find out what happened. If multiple services are crashing, it sounds mostly like a hardware issue.
I looked at all the logs, unfortunately I didn’t find anything special. There were logs after restarting MariaDB, but these errors appeared due to the fact that MariaDB configs were missing. I don’t know what to do next
Maybe the configs disappeared because I restarted MariaDB during the execution of CRON v-update-sys-hestia-all
I have the same problem too. Two servers have been shutting down the service for about 10 days. The log files show no abnormalities. After a restart everything works again without problems. Only the Internet services are no longer running. The server as a whole is technically running. Basic version on both Debian 10. Maybe the problem also occurs with other users? The problem does not exist under Ubuntu 18.04.
Best regards
Tom
