Partitioning on RHEL

[Ansar Mohammed]

My 2c

1. If you have six hard disks, consider raid 1+0. (especially on a db
server)
2. If you have an instance where you need to page 10gb of memory to disk, it
probably means you have other, bigger issues. i.e what value does a 10gb
swap partition/file give you? That 2xRAM theory was created 10-12 years ago
when we had 8-32MB RAM on a system. 
3. Swap files are as of 2.6 as fast as swap partitions and they can be moved
around. 
4. Are you running the x64 edition of RHEL?

Subject: [TLUG]: Partitioning on RHEL

Hello

I have a requirement to setup a Dell server with RHEL 5 and Oracle. The
server has six hard disks configured as RAID 1.

The server has 8GB of physical RAM. The disk size of each RAID 1 is 139GB

I am recommending the following partition sizes and swap size.

/                              10GB
/boot                        100-500MB
/var                           2GB
/opt                           2GB 
swap                         10GB


I have calculated swap size using the following formula:

Upto 2GB RAM ----> double the swap size  ---> 4GB
Add the remaining 6GB for a total swap size of 10GB


Just need confirmation if this is an adequate partitioning scheme for an
Oracle database server running on Linux.


Thank you in advance.
