   > We change the default value to 0, user still can modify it to some other 
value, for example "1", based on their own needs.
   
   We should strive for intuitive configurations out of the box to help 
usability as much as possible. IMO `-1` is expected behavior and will not lead 
to a surprise node shutdown.
   
   > -1 means even 19 disks fails, the datanode is still running, the 
administrator will not know that if he doesn't pay attention to that.
   
   > The DNs should be monitored for disk failures and they should be 
investigated. It should not need a DN to shutdown to make that happen.
   
   This is the real problem: we do not have a good alerting system for disk 
failures. A new Recon page (HDDS-11840), dashboards, and changes like #7266 can 
all remediate this problem without introducing potentially surprising config 
changes.
