The 4th Chapter Linux disk partitioning scheme
Scenario 1-For data not important
/boot boot partition 200M (CentOS 7 1G)
Swap swap partition <8g 1.5G

=8g 8G
/root partition all remaining

Scenario 2-Suitable for data importance
/boot boot partition 200M (CentOS 7 1G)
Swap swap partition <8g 1.5G

=8g 8G
/root Partition 20-200g
/data Data Partition all remaining

Scenario 3-Don't know if it's important
/boot boot partition 200M (CentOS 7 1G)
Swap swap partition <8g 1.5G

=8g 8G
/root Partition 20-200g
Remaining unallocated who is left to use who is assigned
