    RHEL Software RAID 5


    Hi all,

    Is it possible for me to do a linux software raid 5 at disk level rather than partition level/slicing?

    E.g. Given 3 disks: /dev/sda, /dev/sdb and /dev/sdc, I configure them under raid 5 with /dev/md0 during installation, will the OS recognize /dev/md0 as the virtual disk (after raid)? and will the kernel still boots up after installation?


    Which is a better resolution? S/W RAID at partition or disk level?

    Kindly advise.

    Thanks,

    i would say disk level because you are taking an entire disk over a small insignificant partition, plus the throughput will be a little better. My advice is to go get a cheap H/W RAID card and ditch the software raid
