    Os disk vs Database disk

    Hi Friends,

    One of our Production (to be) server (DELL poweredge for Oracle 10g DB , Linux) was pre-configured by the hardware ventor(of disk raiding).

    It has 4x70Gb disk.
    The first disk (70Gb) was allocated to the OS (/root /boot /swap /tmp etc)
    The 3 disk was allocation to oracle database and was raid10 configured for data protection.

    My question is, Is it a good setup....or a normal setup....or a standard setup...or an acceptable setup?

    I am just curious why the engr vendor did not include the OS disk in the raid? since the System/boot/root files are just as important as the oracle database files.
    =====

    Can we add another disk on slot #4 (for mirroring the OS/boot ) without destroying the current set-up? You know, the applications and database is already installed and tested...ready for production. We are just being audited for QA.

    Please shed lights on this matter.

    Thanks a lot

    Hi

    Do you use some kind of Logical Volume Manager as well then you can go ahead and do a mirror of the root disk.

    This primarily should be a responsibility of a System Administrator.

    You can mirror a root disk if you want to.

    Also it would be a best practice to seperate out the root file system and other filesystem like swap.
