We're in the process of testing Open-E. In our lab I have setup a server with two 750 GB drives. The server hardware sees two drives. When I went to go install Open-E is sees both drives. After I've installed and logged into the web interface it's only seeing the 1st drive. I've done a rescan but it only sees one drive.
How do I get Open-E to see the second drive? Just for testing I'd like to set up one big RAID-0 drive.
Open-e only works with "physical volumes" or what it sees as physical volumes. If you've made a raid-0 with two drives, you are presenting one Volume that Open-e sees as one physical volume.
The other possibility is that you've not done any RAID setup so far, and you actually installed the OS on the 1st Volume, and in the web interface you are just seeing the second. This is because the Operating System will install and "take over" the first Volume it sees.
This means the first drive has the Operating System and you cannot do anything else with that first drive.
You could just buy a small flash USB drive and make that your boot volume and then make a raid 1 or buy more drives and make a raid 10.
If your array controller has some good utilities, you should be able to present the Array as Logical Volumes. I have not yet been successful at this myself.
I also strongly suggest against a raid-0. If one drive fails, you lose everything.
It's only in our lab and only for testing, so ignore the fact that it's RAID-0.
Physically we have 2x750 GB hard drives. you are correct that OpenE is installed on 2 GB of the first drive. So you're saying that I can't use the remainder of the drive + the 2nd drive to create a RAID-0? It's not a biggie as this is just for testing but it seems really odd.
