There is something strange between mariadb and qemu-ga on debian 11 (Virtual Machine).
When mariadb is running, you cannot backup a running virtual machine (snapshot).
Host sends the command "fs-freeze" to qemu-ga but it does not work properly.
it hangs the entire VM
Affected mariadb version: 10.6.5 and 10.7.1
Not affected: 10.5.13 (and 10.6.5 on Centos 8 Stream)
My test procedure.
- Install Debian 11 in VM on Proxmox VE.
- Install mariadb from https://mariadb.org/download/?t=repo-config&d=Debian+11+%22Bullseye%22&v=10.6
- run mysql < employees.sql from https://github.com/datacharmer/test_db
- create backup vm (snapshot) in proxmox
