Hi,
I have been trying to set up a Raid 1 mirror using Redhat 6.0 using
stock kernel and raidtools that are included on their CD. I have tried
to follow the Software How-To & read all the newsgroups etc. including
linux-raid archives. I am not a newbie to computers but I am to linux. I
can follow directions if they are correct, I have read in the newsgroups
or have been told by RedHat (using 30day phone support) many conflicting
directions.
I would like to use stock RH 6.0 kernel & raidtools as this is what I
purchased from them with Raid 0,1,5 support.
Has anyone been able to make this work, and if so how?
Here are the system specs. & files:
