MariaDB on ananke impacted Wednesday 26th June 2024 19:19:09

While ananke itself is working fine, its MariaDB instance seems to hang. We're checking things out.

Recovery is done, system is up and running. MariaDB works fine again. As it didn't even react to a SIGKILL and completely blocked even a shutdown, we had to hard-reset ananke. Afterwards, MariaDB was running fine; tables are undergoing a consistency check. There's no indication of circumstances that could have led to this situation, so we suspect a rare bug in MariaDB itself. No other hosts were affected, and the underlying storage system is completely healthy with no errors.

The system needs to be rebooted and will reappear in a few minutes.
