Database service offline without warning

[Jan Gils]

Today a client complained that he/she couldn't change their status on the 3CX app. Everything seems to work, but when they click on the top right corner to change their status, nothing happens after confirming with the "done" button. We checked with other clients and no-one was able to change status.

After investigating, the "3CX PhoneSystem Database Server" had stopped, without warning (email?). It's the latest version of 3CX for Debian.

When looking in the CLI, we notice many SATA read errors (although it's running in a Virtual machine on a NAS).

Some questions:

1. Why wasn't an email sent that the service was stopped? (Normally we get these emails)
2. What's the best action to do to avoid these SATA read errors.

Sounds like either the virtual disk or the physical disk the VD sits on has errors or is corrupted.

If the VD has errors then the best way is a reboot of the VM forcing fsck - https://linuxconfig.org/how-to-force-fsck-to-check-filesystem-after-system-reboot-on-linux

If the file on the host containing the VD is damaged or the host drive it sits on is damaged or failing you may have larger problems and I hope you have a backup to hand...
