I'm new so please forgive me if i'm posting against the rules or something like that. I found some topics that are a bit related, but none with raid 10.
I'm going to switch from Windows server to Ubuntu 12.04 (finally !!!), but now I have a question:
I have a 128 GB SSD, that i want to use for the main OS, and I have four 1TB drives, that I want in a raid 10 configuration for all my data.
I already tried to install, but after the installation, i rebooted and then i get the raid configuration screen (that said that there aren't any raid drives), and then nothing but a black screen with a flickering cursor a the top left (as far as i know that means the isn't any OS detected).
So i booted in to recovery from the USB and from the [partition disk] menu, I see that my partition on the SSD is set to {not used}, but I'm sure I set it correctly before. The same is applying for the RAID volume.
What is the best thing I can do now ?
EDIT: @psusi, htnx for your replay. In the Intel raid configuration manager, I added all the drives to a raid 10 (0+1) configuration, after that I started the installation and Ubuntu auto detected the raid and added it to my partitioning list. Then U just mounted the raid partition to /home and made 2 new partitions on my SSD (boot and swap) and mounted the boot part. on /
here is the output:
~ # dmraid -s
**** Group superset isw_hjabdiead
--> Superset
name : isw_hjabdiead_Data
size : 3711742464
stride : 128

Ps: sorry can't get that code block working correctly :p
sudo dmraid -s
and edit the output into your question.-p o2
switch tomdadm
, and you'll also want an 8 MB or so chunk size ), and it has the read performance of raid0, so that would make it about twice as fast as using the fakeraid.dmraid -s
doesn't see it any more, and install from there.
