Question

Raised to the maximum diskstats_utilization / vg0_root, what does this mean and do I need to do something?
Somewhere they write that everything is OK and nothing terrible, but still.

It means that your file operations almost hit the ceiling in terms of media bandwidth. If you like everything, then you can not worry about a week.
Considering the annual schedule - soon (months) the load on the server will exceed the capabilities of the storage system and the brakes will begin. So it makes sense, while still calmly, to look for the reasons for such a load, to engage in optimization, scaling.
If the database is to blame, you can try to transfer it to a separate server or do master-slave replication, then the master will be loaded mainly for writing, and the slave more for reading. But it makes sense if you have much more reads than writes.
