I would like to know what partitioning scheme in RHEL7 is more recommended to configure on a server with little disk space where an Oracle 18c database will be installed. On the RedHat site they recommend a scheme similar to this:

/ -> 15 GB

/ boot -> 250 MB

/ home-> 8 GB

/ tmp -> 4 GB

/ u01 -> 50 GB

/ usr -> 5 GB

/ var -> 8 GB

My doubt is that the server only has 2 local 25GB SSDs (after raid 1 there is less, around 23). I have a SAN available with enough capacity for the deployment of the database but I would like to know how it is more advisable to partition the operating system on those disks independently of the fact that later I can enlarge the mount points with capacity presented from the SAN, Oracle recommends a swap 16GB (the ram has a capacity of 64GB). Please I am a little new to this and would appreciate any recommendation. Thank you very much in advance for your responses.

I don't see the need for all those partitions. /boot was needed when PC hardware could only boot from a small partition near the start of the disk. Some of the others you may choose to put on different types of storage (HDD, SDD, raid, no-raid).

I have / and /home. I keep these separate, so that I can more easily upgrade/change the OS. If it is a server, where you won't be using /home. Then you don't need that ether.

However keeping OS and data separate is a good idea, but there is more than one way to do it.

  • /home is not required, either; all can go in root
