btrfs, while improved a lot in the past years, still hits some issues, 
though it depends on the usage case and the kernel. Many people, 
including me, run it without and data consistency issues for years on 
many servers.

As mentioned before - a lot of depends on the kernel in use. Your kernel 
is 4.16.x, which, by btrfs standards, is quite old and outdated.

Ubuntu makes it easy to use a newer kernel:

While for systems without btrfs I'd rather stick with a distribution 
kernel, for systems with btrfs - I'd typically use a ppa kernel from 
above.
