Has anyone been successful accessing (read and write) an Intel RST raid array from both Windows and Ubuntu on a dual boot PC? I have a single PC with 6 drives:
- Ubuntu O/S (m2)
- Windows O/S (SSD)
- 4 member Raid 5 array (HDD) with data on it. Formatted in NTFS.
I am wanting to build a raid 5 array of the 4 data drives that I can access from both Windows 11 and Ubuntu 22.10 depending on which O/S I boot at the time. I was trying to use the motherboard RST in Windows and mdadm in Ubuntu, but have not been successful.
I started with building the RST array in Windows and was able to do that successfully. But when I mount that using mdadm in Ubunutu, it does not recognize the meta data.
If someone has has a shared raid 5 array using another mechanism, I would be interested in how they did that too.
I am not wanting to purchase a h/w raid controller.
I have logged a support ticket with Intel. They initially replied that there is a driver issue when sharing between the two O/S. But when I sent them an Intel document that makes it appear to be possible, they asked for time to research further. Why I wait for their reply, I thought I would ask here.
So I just wanted to see if anyone was able to share a raid 5 array in a dual boot PC? Or if anyone has a different mechanism. I prefer Ubuntu mdraid (without RST) as that allows me to add/change storage overtime. But I don't see a way to access an mdadm raid set when booted in windows. Any suggestions?
